user: Croatia’s national television programme is broadcasting an entertainment show titled “I Love Croatia”, modeled on the licensed format I love my country. In this show two teams of celebrities and public figures play various games which require knowledge about Croatia. One of the games is Happy Birthday, which will be used in this task, although somewhat altered.

Eight players numbered one through eight are seated in a circle (see picture). One of them is holding a box which will explode after 3 minutes and 30 seconds from the beginning of the game when some colorful confetti will be blown out. The game begins with a question to the player holding the box. If the players answers incorrectly or skips the question, he is immediately given the next question. If the player answers correctly, he passes the box to the first player seated on his left and then that player gets the next question.

You are given the numbered label of the player who has the box in the beginning and the outcomes of the first $N$ questions asked. Determine the numbered label of the player who had the box when it finally exploded. The question outcome is described with the following data - time passed from the beginning of the question being asked to the moment an answer was given and whether the answer was true (“T”), false (“N”) or skipped (“P”). The time between giving the answer and asking the next question shouldn’t be taken into consideration, as well as time necessary for the box to be passed to the next player. The box will surely explode on a player’s turn.

-----Input-----
The first line of input contains a positive integer $K$ ($1 \leq K \leq 8$), the numbered label of the player who has the box initially. The second line of input contains a positive integer $N$ ($1 \leq N \leq 100$), the number of questions asked during the game. Each of the following $N$ lines contains a positive integer $T$ ($1 \leq T \leq 100$), time passed from the beginning of the $i$-th question being asked to the moment an answer was given, measured in seconds, and a single character $Z$ (“T”, “N” or “P”), the type of answer given.

-----Output-----
The first and only line of output must contain the numbered label of the player who had the box when it finally exploded.

user: In the kingdom of Winterfield, there are several cities and each pair of cities is connected by exactly one old dirt road. The king of Winterfield has decided that he will upgrade some of those roads. The set of roads that he upgrades must be such that it is possible to get from any city in the kingdom to any other city via some sequence of upgraded roads.

Because there is so much snow in Winterfield, the king has also decided to plow some of those upgraded roads. The local plow company, Mr. Plow, and the king have agreed on the following: the king labels each of the upgraded roads $1, 2, \dots , m$ (the label of each road is the number of gold pieces it costs to plow that road) and each road must receive a distinct label. Mr. Plow will plow a set of upgraded roads so that it is possible to get from any city to any other city via some sequence of plowed roads. Mr. Plow will select the cheapest possible set of roads that satisfies the above condition.

For example, if the kingdom has six cities and the king decides to upgrade and label the 8 bolded dirt roads as follows, then Mr. Plow will then plow the roads with labels 1, 2, 3, 4 and 6 (costing a total of 16 gold pieces).

The king has decided on the number of roads to upgrade, but he is not sure how to label them, so he has turned to Barney (the kingdom’s mathematician) to help decide. However, the king is unaware that Barney is actually invested in Mr. Plow, so Barney will choose the set of roads to upgrade and how to label them so that the total cost is as large as possible. What is the maximum cost of plowing the roads?

-----Input-----
The input consists of a single line containing two integers $n$ ($2 \leq n \leq 1000000$), which is the number of cities, and $m$ ($n-1 \leq m \leq \frac{n(n-1)}{2}$), which is the number of roads to be upgraded.

-----Output-----
Display the maximum possible cost of plowing the roads following the rules above.

user: A close friend of yours, a duck with financial problems, has requested your help with a matter that will help him pay off his debts. He is the nephew of an extremely wealthy duck, who has a large vault, filled with mountains of coins. This wealthy duck has a certain coin in his possession which has a lot of sentimental value to him. Usually, it is kept under a protective glass dome on a velvet cushion.

However, during a recent relocating of the coins in the vault, the special coin was accidentally moved into the vault, leading to an extremely stressful situation for your friend’s uncle. Luckily, the coin has recently been located. Unfortunately, it is completely opposite to the entrance to the vault, and due to the mountains of coins inside the vault, actually reaching the coin is no simple task.

He is therefore willing to pay your friend to retrieve this coin, provided that he brings his own equipment to scale the mountains of coins. Your friend has decided he will bring a ladder, but he is still uncertain about its length. While a longer ladder means that he can scale higher cliffs, it also costs more money. He therefore wants to buy the shortest ladder such that he can reach the special coin, so that he has the largest amount of money left to pay off his debts.

The vault can be represented as a rectangular grid of stacks of coins of various heights (in meters), with the entrance at the north west corner (the first height in the input, the entrance to the vault is at this height as well) and the special coin at the south east corner (the last height in the input). Your avian companion has figured out the height of the coins in each of these squares. From a stack of coins he can attempt to climb up or jump down to the stack immediately north, west, south or east of it. Because your friend cannot jump or fly (he is a very special kind of duck that even wears clothes), successfully performing a climb of $n$ meters will require him to bring a ladder of at least $n$ meters. He does not mind jumping down, no matter the height; he just lets gravity do all the work.

-----Input-----
The first line contains two integers: the length $M$, and the width $N$ of the vault, satisfying $1 \leq M,N \leq 1000$.

The following $M$ lines each contain $N$ integers. Each integer specifies the height of the pile of coins in the vault at the corresponding position. (The first line describes the north-most stacks from west to east; the last line describes the south-most stacks from west to east). The heights are given in meters and all heights are at least $0$ and at most $10^9$ (yes, your friend’s uncle is very rich).

-----Output-----
Output a single line containing a single integer: the length in meters of the shortest ladder that allows you to get from the north west corner to the south east corner.

user: Pero has negotiated a Very Good data plan with his internet provider. The provider will let Pero use up $X$ megabytes to surf the internet per month. Each megabyte that he doesn’t spend in that month gets transferred to the next month and can still be spent. Of course, Pero can only spend the megabytes he actually has.

If we know how much megabytes Pero has spent in each of the first $N$ months of using the plan, determine how many megabytes Pero will have available in the $N + 1$ month of using the plan.

-----Input-----
The first line of input contains the integer $X$ ($1 \leq X \leq 100$). The second line of input contains the integer $N$ ($1 \leq N \leq 100$). Each of the following $N$ lines contains an integer $P_ i$ ($0 \leq P_ i \leq 10000$), the number of megabytes spent in each of the first $N$ months of using the plan. Numbers $P_ i$ will be such that Pero will never use more megabytes than he actually has.

-----Output-----
The first and only line of output must contain the required value from the task.

user: A known problem with some microphones is the “hissing s”. That is, sometimes the sound of the letter s is particularly pronounced; it stands out from the rest of the word in an unpleasant way.

Of particular annoyance are words that contain the letter s twice in a row. Words like amiss, kiss, mississippi and even hiss itself.

-----Input-----
The input contains a single string on a single line. This string consists of only lowercase letters (no spaces) and has between $1$ and $30$ characters.

-----Output-----
Output a single line. If the input string contains two consecutive occurrences of the letter s, then output hiss. Otherwise, output no hiss.

-----Examples-----
Sample Input 1:

user: Catherine is a brilliant software engineer, but she has been having difficulty landing a job, despite having submitted a superb resume to dozens of tech companies. After doing some research, she discovered that most tech companies in her area use an algorithm to prescreen resumes by scanning for certain keywords before the resume is even seen by a human. Any resume that does not contain sufficiently many technology-related keywords is automatically rejected!

Catherine has devised a plan to outwit the prescreening algorithm: she intends to cram as many keywords as possible into her resume to maximize her chances of passing the prescreening process. As a first step, she has downloaded a list of the most common tech buzzwords from an online data bank that includes entries such as “machine learning”, “Big data”, “AI”, “C++”, “Neural-network”, “unix”, “cryptography”, etc. (Note that keyword sometimes really means keyphrase.)

In the early stages of drafting her new resume, Catherine notices that many keywords from the data bank are very similar to each other (e.g., “Machine-learning” vs. “machine learning”, or “MySQL” vs. “MySql”). Since she suspects that including nearly identical keywords won’t help her fool the prescreening algorithm, she wants to filter out such similar keywords in order to save room on her resume. Catherine considers two keywords $k_1$ and $k_2$ to be similar if, after replacing hyphens with spaces and ignoring capitalization, $k_1$ is the same as $k_2$.

Can you help Catherine craft the perfect resume to land her a job?

-----Input-----
The first line contains an integer, $n$ $(1 \leq n \leq 40000)$, the number of keywords in the data bank. This is followed by $n$ lines, each of which contains a keyword string $k$ that is between $1$ and $25$ characters in length (inclusive). All characters in a keyword are guaranteed to fall in the $[32, 126]$ ASCII range, and no keyword begins or ends with a space or a hyphen.

-----Output-----
Output a single line containing the number of (pairwise) non-similar keywords in the data bank.

user: Seven Wonders is a card drafting game in which players build structures to earn points. The player who ends with the most points wins. One winning strategy is to focus on building scientific structures. There are three types of scientific structure cards: Tablet (‘T’), Compass (‘C’), and Gear (‘G’). For each type of cards, a player earns a number of points that is equal to the squared number of that type of cards played. Additionally, for each set of three different scientific cards, a player scores $7$ points. 

For example, if a player plays $3$ Tablet cards, $2$ Compass cards and $1$ Gear card, she gets $3^2 + 2^2 + 1^2 + 7 = 21$ points.

It might be tedious to calculate how many scientific points a player gets by the end of each game. Therefore, you are here to help write a program for the calculation to save everyone’s time.

-----Input-----
The input has a single string with no more than $50$ characters. The string contains only letters ‘T’, ‘C’ or ‘G’, which denote the scientific cards a player has played in a Seven Wonders game.

-----Output-----
Output the number of scientific points the player earns.

-----Note-----
Seven Wonders was created by Antoine Bauza, and published by Repos Production. Antoine Bauza and Repos Production do not endorse and have no involvement with the ProgNova contest.

user: Jonas is developing the JUxtaPhone and is tasked with animating the compass needle. The API is simple: the compass needle is currently in some direction (between $0$ and $359$ degrees, with north being $0$, east being $90$), and is being animated by giving the degrees to spin it. If the needle is pointing north, and you give the compass an input of $90$, it will spin clockwise (positive numbers mean clockwise direction) to stop at east, whereas an input of $-45$ would spin it counterclockwise to stop at north west. 

The compass gives the current direction the phone is pointing and Jonas’ task is to animate the needle taking the shortest path from the current needle direction to the correct direction. Many ifs, moduli, and even an arctan later, he is still not convinced his minimumDistance function is correct; he calls you on the phone.

-----Input-----
The first line of input contains an integer $n_1$ ($0 \le n_1 \le 359$), the current direction of the needle. The second line of input contains an integer $n_2$ ($0 \le n_2 \le 359$), the correct direction of the needle.

-----Output-----
Output the change in direction that would make the needle spin the shortest distance from $n_1$ to $n_2$. A positive change indicates spinning the needle clockwise, and a negative change indicates spinning the needle counter-clockwise. If the two input numbers are diametrically opposed, the needle should travel clockwise. I.e., in this case, output $180$ rather than $-180$.

user: Getting a business permit in Kafkatown requires a trip to City Hall. There you are given a permit form that must be signed by $K$ city clerks whose names are printed at the bottom of the form.

Entering the clerks’ room, you find a long line of people working their way down a narrow aisle along the clerks’ desks. Their desks are arranged in increasing numeric order. The aisle is so narrow that the line is forced to shuffle forward, single file, past each of the clerks’ desk in turn. Once in the line you cannot leave, back up, or change positions with other people.

As you present your permit for a signature, you are told that no clerk will sign unless all of the signatures above his or her name on the permit form have already been filled in. To your dismay, the clerks’ desks are not arranged in the same order as the names on your form.

How many times do you need to pass through the line until you can get your permit?

-----Input-----
The first line of input contains an integer $K$, the number of signatures you need to collect ($1 \leq K \leq 100$).

This is followed by $K$ lines of input, each containing an integer in the range $1\ldots 100$, indicating the desk numbers of each of the clerks whose signature you need, in the order that they appear on your form. (Clerks whose signatures are not needed on your form are omitted from this list.)

For example, the input

    5 1 23 18 13 99

means that you need $5$ signatures. The first must come from the clerk in desk #$1$, the next from the clerk in desk #$23$, and so on, with the final signature coming from the clerk in desk #$99$.

No desk number appears more than once in the input.

-----Output-----
Print a single line containing an integer denoting the number of passes you need to make through the line until you can collect the signatures that you need.

user: A mysterious circular arrangement of black stones and white stones has appeared. Ming has been tasked with balancing the stones so that only one black and one white stone remain.

Ming has two operations for balancing the stones:
 - Take some consecutive sequence of stones where there is exactly one more black stone than a white stone and replace the stones with a single black stone
 - Take some consecutive sequence of stones where there is exactly one more white stone than black stone and replace the stones with a single white stone

Given a circular arrangement, determine if it is possible for Ming to balance the stones.

-----Input-----
Each input will consist of a single test case. Note that your program may be run multiple times on different inputs. The input will consist of a single string $s$ ($1 \le |s| \le 10^5$), with only the characters capital ‘B’ and ‘W’. The stones are arranged in a circle, so the first stone and the last stone are adjacent.

-----Output-----
Output $1$ if it is possible for Ming to balance the stones with his rules. Otherwise, output $0$.

user: While working a night shift at the university as a janitor, you absentmindedly erase a blackboard covered with equations, only to realize afterwards that these were no ordinary equations! They were the notes of the venerable Professor E. I. N. Stein who earlier in the day solved the elusive maximum quadrilateral problem! Quick, you have to redo his work so no one noticed what happened. 

The maximum quadrilateral problem is quite easy to state: given four side lengths $s_1, s_2, s_3$ and $s_4$, find the maximum area of any quadrilateral that can be constructed using these lengths. A quadrilateral is a polygon with four vertices.

-----Input-----
The input consists of a single line with four positive integers, the four side lengths $s_1$, $s_2$, $s_3$, and $s_4$.

It is guaranteed that $2s_ i < \sum _{j=1}^4 s_ j$, for all $i$, and that $1 \leq s_ i \leq 1000$.

-----Output-----
Output a single real number, the maximal area as described above. Your answer must be accurate to an absolute or relative error of at most $10^{-6}$.

user: The ancient and mysterious Apaxian civilization, which we most certainly did not make up, continues to confound the researchers at the Oriental Institute. It turns out that the Apaxians had a peculiar naming system: the more letters in your name, the higher your status in society. So, in Apaxian society, robert was probably a lowly servant, and robertapalaxiamethostenes was likely a High Priest or Minister. Even more than that, Apaxians valued the number of adjacent letters that were the same in a name. So, while robert continues to be an unimpressive name, roooooooooobert probably elicited cheers and applause wherever he went.

Unfortunately, this makes the task of reading Apaxian scrolls very cumbersome, especially when you consider that a particularly famous Apaxian queen had ten thousand consecutive a’s in her name. Legend has it that she was already two years old by the time the Royal Herald finished announcing her birth.

To make the Oriental Institute’s life easier, the Department of Computer Science has offered to convert the Apaxian scrolls into a more readable format. Specifically, we will be taking Apaxian names and replacing all consecutive runs of the same letter by a single instance of such letter.

So, for example, the compact version of roooobert would be robert, where the four consecutive o’s have been replaced with a single o. Similarly, the compact version of rrrooobbbert would also be robert. On the other hand, the compact version of robert is still robert.

-----Input-----
The input contains a single name. Each name contains only lowercase letters (a–z), no whitespace, a minimum length of 1 character, and a maximum length of 250 characters.

-----Output-----
The output contains the compact version of the name: any time the same letter appears two or more times in sequence, it must be replaced by a single instance of that letter.

-----Examples-----
Sample Input 1:
robert
Sample Output 1:
robert

Sample Input 2:
rooobert
Sample Output 2:

user: Peter is expecting a large shipment of fuel oil, but he has a small problem (doesn’t everyone in these programming problems!). The only containers he has are a set of large bottles (each with the same volume) and a set of smaller bottles (also each with the same, but smaller volume). Given the volume of the shipment of oil, he would like to store the oil in the bottles so that
 - all of the oil is stored,
 - each bottle is filled to the top, and
 - the minimum number of bottles is used.

While Peter thinks he has solved this problem for his given bottle sizes, he often spends hours wondering what would happen if his bottles had different volumes (apparently Peter doesn’t lead the most exciting life).

-----Input-----
The input consists of a single line containing three positive integers $s$$v_1$ $v_2$, where $s \leq 10^6$ is the volume of the shipment, and $v_1, v_2 \leq 10^6$ are the volumes of the two types of bottles, with $v_1 > v_2$.

-----Output-----
Output the number of bottles of size $v_1$ and the number of bottles of size $v_2$ which satisfy Peter’s two conditions. If the conditions cannot be met, output Impossible.

user: Mirko got his driver’s license! To celebrate that joyous occasion, his parents bought him his first car: a monster truck! Mirko found out that even though having a car that can squash all other cars is nice in traffic jams, parking a car that is the size of $4$ normal cars can be a bit tricky.

His friend, Slavko, works part time in the city parking company. He periodically sends Mirko a map of the city with occupied parking spaces marked. The map can be represented as a table with $R$ rows, $C$ columns each. Each cell can contain a building (symbol ‘#’), a parked car (symbol ‘X’) or a free parking space (symbol ‘.’). A monster truck is quite huge, $2$ by $2$ cells to be exact.

Help Mirko calculate the number of possible parking spaces grouped by the number of cars he needs to squash to park in them. We are only interested in the number of cars Mirko will squash on the parking space, not the number of cars he will squash on the way over. However, Mirko can’t park on a building. Not even a monster truck is large enough to squash buildings!

-----Input-----
The first line of input contains two integers, $R$ and $C$ ($2 \leq R, C \leq 50$), the number of rows and columns of the map. The next $R$ lines contain $C$ characters each. Only characters ‘#’, ‘X’ and ‘.’ appear in the input. Note that ‘X’ will always be capital.

-----Output-----
The output consists of five lines, the total number of parking spaces Mirko can park on if he squashes $0$ cars (first line), $1$ car (second line), $2$ cars (third line), $3$ cars (fourth line), $4$ cars (fifth line).
