user: A New Alphabet has been developed for Internet communications. While the glyphs of the new alphabet don’t necessarily improve communications in any meaningful way, they certainly make us feel cooler.

You are tasked with creating a translation program to speed up the switch to our more elite New Alphabet by automatically translating ASCII plaintext symbols to our new symbol set.

The new alphabet is a one-to-many translation (one character of the English alphabet translates to anywhere between $1$ and $6$ other characters), with each character translation as follows:

For instance, translating the string “Hello World!” would result in:[-]3110 \/\/0|Z1|)!

Note that uppercase and lowercase letters are both converted, and any other characters remain the same (the exclamation point and space in this example).

-----Input-----
Input contains one line of text, terminated by a newline. The text may contain any characters in the ASCII range $32$–$126$ (space through tilde), as well as $9$ (tab). Only characters listed in the above table (A–Z, a–z) should be translated; any non-alphabet characters should be printed (and not modified). Input has at most $10000$ characters.

-----Output-----
Output the input text with each letter (lowercase and uppercase) translated into its New Alphabet counterpart.

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

user: Alice and Bob are playing a new game of stones. There are $N$ stones placed on the ground, forming a sequence. The stones are labeled from $1$ to $N$.

Alice and Bob in turns take exactly two consecutive stones on the ground until there are no consecutive stones on the ground. That is, each player can take stone $i$ and stone $i+1$, where $1 \leq i \leq N - 1$. If the number of stone left is odd, Alice wins. Otherwise, Bob wins.

Assume both Alice and Bob play optimally and Alice plays first, do you know who the winner is?

-----Input-----
The input contains an integer $N$ $(1 \leq N \leq 10000000)$, the number of stones.

-----Output-----
Output the winner, “Alice” or “Bob” (without the quotes), on a line.

user: Mirko purchased a new microprocessor. Unfortunately, he soon learned that many of his programs that he wrote for his old processor didn’t work on the new processor.

Deep inside the technical documentation for both processors, he found an explanation. In order to work faster, the new processor imposes certain constraints on the machine code of programs, constraints that never existed on the previous model.

The machine code of a processor consists of instructions that are executed sequentially. Each instruction uses a byte of memory. Also, instructions can have zero or more parameters, each of which uses an additional byte of memory. In machine code, parameters immediately follow an instruction.

When formatted as text, machine code instructions are uppercase letters, while parameters are lowercase letters. For example:

A

b

c

b

B

c

c

C

D

e

f

g

h

This program consists of four instructions; the first takes three parameters, the second two, the third none and the fourth takes four parameters. The program uses $13$ bytes of memory.

The new processor model fetches memory in four-byte chunks so each instruction must start at a memory address that is divisible by four (the first byte in memory is address $0$). To achieve that, we can insert NOP (no operation) instructions into the old program, instructions that do nothing and are not limited to memory locations divisible by four. The above program, adapted to run on the new processor, can look like this:

A

b

c

b

B

c

c

NOP

C

NOP

NOP

NOP

D

e

f

g

h

The instructions A, B, C and D are now at memory locations $0$, $4$, $8$ and $12$, which satisfies the processor’s constraints.

Write a program that determines the smallest number of NOP instructions that need to be inserted for the given program to work on the new processor model.

-----Input-----
The input contains the machine code of the program written for the old processor model. The program will consist of at most $200$ English letters.

The program will always start in an instruction, i.e., the first letter in the machine code will be uppercase. If an instruction appears more than once in the machine code, it will always take the same number of parameters.

-----Output-----
Output the smallest number of NOP instructions needed to adapt the program for the new processor.

user: When determining the age of a bull moose, the number of tines (sharp points), extending from the main antlers, can be used. An older bull moose tends to have more tines than a younger moose. However, just counting the number of tines can be misleading, as a moose can break off the tines, for example when fighting with other moose. Therefore, a point system is used when describing the antlers of a bull moose. 

The point system works like this: If the number of tines on the left side and the right side match, the moose is said to have the even sum of the number of points. So, “an even $6$-point moose”, would have three tines on each side. If the moose has a different number of tines on the left and right side, the moose is said to have twice the highest number of tines, but it is odd. So “an odd $10$-point moose” would have $5$ tines on one side, and $4$ or less tines on the other side.

Can you figure out how many points a moose has, given the number of tines on the left and right side?

-----Input-----
The input contains a single line with two integers $\ell $ and $r$, where $0 \le \ell \le 20$ is the number of tines on the left, and $0 \le r \le 20$ is the number of tines on the right.

-----Output-----
Output a single line describing the moose. For even pointed moose, output “Even $x$” where $x$ is the points of the moose. For odd pointed moose, output “Odd $x$” where $x$ is the points of the moose. If the moose has no tines, output “Not a moose”

user: Good old Marko came across a new feature on his mobile phone – T9 input! His phone has a keyboard consisting of numbers looking like this:

1

2

3 

abc

def

4

5

6

ghi

jkl

mno

7

8

9

pqrs

tuv

wxyz

In order to input a word using this keyboard, one needs to press a key multiple times for the required letter. More specifically, if the required letter is the first letter mapped to the key, one key press is needed, if it’s the second, two key presses are needed and so on. For instance, if we want to input the word “giht”, we will press the following keys: g-4 i-444 h-44 t-8. The new possibility Marko discovered enables you to input text more easily because you don’t need several presses per letter anymore, just one. The software will try to figure out what word from the dictionary you are trying to input.

Marko is quite sceptical of new technologies (at least new for him) and he is afraid that errors will be frequent. That is the reason why he decided to test his hypothesis that the errors are frequent. Marko knows by heart the whole dictionary in the mobile phone. The dictionary consists of $N$ words consisting of lowercase letters from the English alphabet, the total length of the word not exceeding $1000000$ characters. He will give an array of key presses $S$, of total length at most $1000$, and wants to know how many words from the dictionary can be mapped to the given array of key presses if the T9 input feature is used.

-----Input-----
The first line of input contains the integer $N$, the number of words in the dictionary. ($1 \leq N \leq 1000$). Each of the following $N$ lines contains a single word. The last line of input contains the string $S$ ($1 \leq |S| \leq 1000$) consisting of digits $2$–$9$.

-----Output-----
The first and only line of output must contain the number of words from the dictionary possible to construct from the letters on the keys determined by the string $S$.

user: “Peter Pan frames” are a way of decorating text in which every character is framed by a diamond- shaped frame, with frames of neigbhouring characters interleaving. A Peter Pan frame for one letter looks like this (‘X’ is the letter we are framing):

..#..
.#.#.
#.X.#
.#.#.
..#..

However, such a framing would be somewhat dull so we’ll frame every third letter using a “Wendy frame”. A Wendy frame looks like this:

..*..
.*.*.
*.X.*
.*.*.
..*..

When a Wendy frame interleaves with a Peter Pan frame, the Wendy frame (being much nicer) is put on top. For an example of the interleaving check the sample cases.

-----Input-----
The first and only line of input will contain at least $1$ and at most $15$ capital letters of the English alphabet.

-----Output-----
Output the word written using Peter Pan and Wendy frames on $5$ lines.

user: The 19th century German mathematician Hermann Minkowski investigated a non-Euclidian geometry, called the taxicab geometry. In taxicab geometry the distance between two points $T_1(x_1, y_1)$ and $T_2(x_2, y_2)$ is defined as:\[ D(T_1,T_2) = \left|x_1 - x_2\right| + \left|y_1 - y_2\right| \]

All other definitions are the same as in Euclidian geometry, including that of a circle:

A circle is the set of all points in a plane at a fixed distance (the radius) from a fixed point (the centre of the circle).

We are interested in the difference of the areas of two circles with radius $R$, one of which is in normal (Euclidian) geometry, and the other in taxicab geometry. The burden of solving this difficult problem has fallen onto you.

-----Input-----
The first and only line of input will contain the radius $R$, a positive integer smaller than or equal to $10000$.

-----Output-----
On the first line you should output the area of a circle with radius $R$ in normal (Euclidian) geometry. On the second line you should output the area of a circle with radius $R$ in taxicab geometry.

Note: Outputs within $\pm 0.0001$ of the official solution will be accepted.

user: At ACME Corp, the seller Robin is selling software like hotcakes. To sell the software, he arranges meetings all over the country. Of course, he always needs to travel there, and sometimes even stay the night. Other times, he decides that a hot dog on the way to a meeting counts as accommodation.

Because Robin is very busy, he hasn’t been able to file his job expenses this month. Eret, the accountant, told him that he could fix it for him, as long as he got the price of all the expenses along with the receipts. Robin did this but misheard him: He has provided a list of all expenses and incomes he has brought in last month, with incomes as positive integers and expenses as negative integers.

Can you help Eret find out how much expenses Robin has paid for the last month?

-----Input-----
The input consist of two lines: One line with the integer $N$, and one line with $N$ integers $k_ i$, representing the numbers Robin has written down.

-----Output-----
Output the sum of all the expenses Robin has paid for the last month.

-----Limits-----
 - $0 \leq N \leq 20000$
 - $-50000 \leq k_ i\leq 500000$ and $k_ i \neq 0$

user: Ante and Goran are preparing $N$ teams of young ambitious students for a student programming competition of students from University of Zagreb. Both of them have one algorithm they have to explain to each team. Of course, both can’t work with the same team at the same time and none of them can work with multiple teams simultaneously.

You are given the time it takes for each team to understand and implement an algorithm. Each algorithm lecture has to be done without interruption. Determine the minimal time required for Ante and Goran to do their lectures!

For additional explanation, consult the sample test clarifications.

-----Input-----
The first line of input contains the integer $N$, the number of teams.

The following line contains $N$ space separated integers, where the $i$’th integer denotes the time required for the $i$’th team to understand and implement an algorithm.

All numbers in the input belong to the interval $[1, 3 \cdot 10^5]$.

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

Clarification of the first example: Each team needs $2$ units of time to understand and implement an algorithm. One of the possible schedules is that Ante gives his lectures to team $1$, team $2$ and team $3$, respectively, and Goran to team $3$, team $1$ and team $2$, respectively.

Clarification of the second example: One of the optimal schedules is that Ante gives lectures to team $2$, team $3$ and team $1$, respectively, but with a pause lasting $1$ unit of time between team $3$ and team $1$. Goran will give lectures to team $1$, team $3$ and team $2$, respectively.

user: Wall Maria has been broken! Eren must evacuate as soon as possible from his house. He must find the fastest route to escape within Wall Maria before the titans rush in. Wall Maria is represented as a $N \times M$ grid in which Eren can move horizontally or vertically.

There are burning houses and buildings which prevent Eren from passing through them. The burning houses and buildings are represented as ‘1’. Unburned or safe areas are represented as ‘0’. There are some areas which can be entered but only from a specific direction. These areas can be represented by either ‘U’, ‘D’, ‘L’, or ‘R’. For example, if there is an ‘R’ that means that area can only be entered from the right neighboring tile within Wall Maria’s grid. Similarly, ‘U’ tiles can only be entered from above, ‘D’ tiles can only be entered from below, and ‘L’ tiles can only be entered from the left.

Eren knows the time $t$ at which the titans will rush in. It takes $1$ unit of time to traverse $1$ zone (which corresponds to $1$ tile in the grid). Once he reaches any border of Wall Maria he is safe.

Eren’s starting position is represented by the letter ‘S’. If Eren escapes at or before time $t$, he is safe. Given his position within Wall Maria determine if it is possible to escape. If it is possible determine the number of zones that must be traversed to lead to the quickest escape.

-----Input-----
The input consists of a single test case. The first line contains three integers $t$ ($1 \le t \le 200$) , $N$ ($1 \le N \le 100$) and $M$ ($1 \le M \le 100$). The rest of N lines will be Wall Maria’s grid containing characters ‘1‘, ‘0‘, ‘S‘, ‘U‘, ‘D‘, ‘L‘, or ‘R‘. There is exactly one ‘S‘ in the input.

-----Output-----
If it is possible to escape Wall Maria, output the minimum number of zones that must be traversed to escape. If it is not possible to escape, print “NOT POSSIBLE”!

user: Young Mislav loves spending time in nature and, most of all, he loves spending time in forests. The fresh air and lovely sounds make the forest his favourite location. Mislav has decided to spend this afternoon in a forest and, because he’s so practical, he’s also decided to stuff himself with food. His belly can contain $C$ amount of food.

He will have the opportunity to eat various fruits of nature (mushrooms, chestnuts, berries, and so on) while walking through the forest. All fruits are mutually different given their type and he’d like to eat as much different fruits as possible, but with the condition that he doesn’t overeat. In other words, the total weight of the fruits he’s eaten must not be larger than $C$. Also, when Mislav decides to start eating, he tries to eat every next fruit if it’s possible to eat it and not overeat. In the case when he doesn’t have the capacity to eat it, he just moves on.

An array of weights of $N$ fruits represents the weight and order of fruits that Mislav came across in the forest. Determine the maximum amount of different fruits that Mislav can eat.

-----Input-----
The first line of input contains two integers $N$ and $C$ ($1 \leq N \leq 1000$, $1 \leq C \leq 1000000$) from the task. The second line contains $N$ integers $w_ i$ ($1 \leq w_ i \leq 1000$) that represent the fruits’ weight.

-----Output-----
The first and only line of output must contain the maximum possible amount of different fruits that Mislav can eat.

user: Rock-paper-scissors is a popular two-player game. In the game, each of the players uses their hand to show one of three symbols: rock, paper or scissors. If both players show the same symbol, the game is a tie. Otherwise, scissors beat paper, paper beats rock and rock beats scissors.

Sven has been studying the psychological intricacies of the game for years and has become a real master at the game, his friends not standing a chance against him in one-on-one games.

With the world championships around the corner, Sven is practicing his skills playing simultaneous games with $N$ of his friends. One such game consists of $R$ rounds. In each round, Sven and each of his friends show one of the three symbols.

When calculating the score, in each round, Sven’s symbol is independently compared to each of his friends’ symbols. Sven scores two points for every win and one point for every tie. Sven does not get points for losing.

Write a program that calculates Sven’s total score, and also his largest possible score had he known in advance all the symbols his friends would show.

-----Input-----
The first line contains the integer $R$ ($1 \le R \le 50$), the number of rounds played.

The second line contains a string of $R$ letters ‘S’, ‘P’ or ‘R’. The string represents symbols that Sven showed in each round. ‘S’ is for scissors, ‘P’ for paper, ‘R’ for rock.

The third line contains the integer $N$ ($1 \le N \le 50$), the number of friends.

Each of the following $N$ lines contains a string of $R$ letters ‘S’, ‘P’ or ‘R’. These are the symbols shown by each of the $N$ friends in each of the $R$ rounds.

-----Output-----
Output Sven’s actual score on the first line.

Output his largest possible score on the second line, assuming his friends didn’t change their symbols.

user: Robin just received a stopwatch from her grandfather. Robin’s stopwatch has a single button. Pressing the button alternates between stopping and starting the stopwatch’s timer. When the timer is on, the displayed time increases by 1 every second.

Initially the stopwatch is stopped and the timer reads 0 seconds. Given a sequence of times that the stopwatch button is pressed, determine what the stopwatch’s timer displays.

-----Input-----
The first line of input contains a single integer $N$ ($1 \leq N \leq 1000$), which is the number of times the stopwatch was pressed.

The next $N$ lines describe the times the stopwatch’s button was pressed in increasing order. Each line contains a single integer $t$ ($0 \leq t \leq 10^6$), which is the time the button was pressed. No two button presses happen on the same second.

-----Output-----
Display still running if the stopwatch’s timer is still running after all button presses were made. Otherwise display the number of seconds displayed on the stopwatch’s timer.

user: For NWERC 2018, the organisers have done something rather special with the balloons. Instead of buying balloons of equal size, they bought one balloon of every integer size from $1$ up to $n$. A balloon of size $s$ has a capacity of $s$ decilitres. 

To avoid inflating the balloons by hand, the organisers also bought $n$ helium gas canisters. Each canister can only be used to inflate one balloon, and must be emptied completely into that balloon (it is not possible to disconnect a canister from a balloon before the canister has been fully used).

Unfortunately the gas canisters were bought at a garage sale, and may contain differing amounts of helium. Some may even be empty! To make the best of this challenging situation, the canisters will have to be paired with the balloons smartly.

The organisers want to assign all of the gas canisters to separate balloons, such that the balloon that is inflated the least (relative to its capacity) still contains the maximum possible fraction of helium inside. What is the maximum such (minimum) fraction that is possible?

Balloons filled beyond their capacity will explode. Explosions are upsetting and must be avoided.

-----Input-----
The input consists of:
 - One line with the integer $n$ ($1 \le n \le 2\cdot 10^5$), the number of balloons and gas canisters.
 - One line with $n$ integers $c_1, \ldots , c_ n$ ($0 \le c_ i \le n$ for each $i$), the amounts of helium in the gas canisters, in decilitres.

-----Output-----
If it is possible to fill all the balloons without any exploding, output the maximum fraction $f$ such that every balloon can be filled to at least $f$ of its capacity. Otherwise, output “impossible”.

Your answer should have an absolute or relative error of at most $10^{-6}$.
