user: John was learning mathematics and was very bored. Jane his best friend gave him a problem to solve. 
The description of the problem was as follows:- 
You are given a decimal number $N$(1<=$N$<=$10^9$) and three integers $A$, $B$, $C$. 
Steps to perform:
1) You have to create a $LIST$. 
2) You have to initialize the $LIST$ by adding N to the $LIST$ as its first element. 
3) Divide$N$ by $A$ and if the first digit of the fractional part is Non-Zero then add this digit to the  $LIST$ otherwise add the first digit of the integral part(Leftmost digit).
(The integer part or integral part of a decimal is the integer written to the left of the decimal separator.  The part from the decimal separator i.e to the right is the fractional part. )
4) Update $N$  by Last element of the $LIST$. 
N = Last element of $LIST$
5) You have to perform the same process from step 3 on $N$ for $B$ and $C$ respectively 
6) Repeat from step 3 
You have to answer$Q$(1 <= $Q$<= 100 ) queries
For each query you are given an integer $i$ (0 <= $i$ <= $10^9$ ). You have to print the element present at the ith position of the $LIST$. 
Help John solve this problem.

-----Input:-----
- The First Line of input contains a single integer $T$ denoting the number of test cases. The description of $T$ test cases follows.
- The First Line of each test case contains the  integer $N$.
- The second line of each test case contains three integers $A$, $B$, and $C$ separated by a space
- The third line of each test case contains an integer $Q$.
- Then the next $Q$ line follows.  
- An integer $i$ (0 <= $i$ <= 10^9 )

-----Output:-----
You have to answer the $Q$ queries in the next $Q$ lines. 

-----Constraints-----
- $1 \leq T \leq 10$
- $1 \leq N \leq 10^9$
- $2 \leq A \leq 10$
- $2 \leq B \leq 10$
- $2 \leq C \leq 10$
- $2 \leq Q \leq 100$
- $0 \leq i \leq 10^9$

-----EXPLANATION:-----
This list is :
$N$ = 56 and $A$ = 3, $B$ = 5, $C$ = 7. 
Initially $LIST$ = $[ 56 ]$
$N$$/$$A$ =  56/3 = 18.666666666666668 
Add 6 to the $LIST$ 
$LIST$ = $[ 56, 6 ]$
$N$ = 6 
$N$$/$$B$ = 6/5 = 1.2 
Add 2 to the$LIST$ 
$LIST$ = $[ 56, 6, 2 ]$
N = 2 
$N$$/$$C$ = 2/7 =0. 2857142857142857
Add 2 to the $LIST$.  
$LIST$ = $[ 56, 6, 2, 2 ]$
$N$  = 2
We have to keep repeating this process. If any of the numbers got by $N$ dividing by either $A$, $B$, $C$ have 0 after the decimal point then we have to take the first digit of the number. 
for example: if we got 12.005 then here we take 1 and add it to the list and then assign N = 1 
Now the queries ask for the elements at index 0, 1, 2, 3 of the $LIST$ which is 56,6, 2, 2
user: You are given an array A of size N. Let us list down all the subarrays of the given array. There will be a total of N * (N + 1) / 2 subarrays of the given array. Let us sort each of the subarrays in descending order of the numbers in it. 

Now you want to sort these subarrays in descending order. You can compare two subarrays B, C, as follows.

compare(B, C):
Append N - |B| zeros at the end of the array B.
Append N - |C| zeros at the end of the array C.
for i = 1 to N:
if B[i] < C[i]:
return B is less than C
if B[i] > C[i]:
return B is greater than C
return B and C are equal.

You are given M queries asking for the maximum element in the pth subarray (1-based indexing).

-----Input-----
The first line of input contains T, the number of test cases.
The first line of each test case contains two space separated integers N and M, denoting the array size and the number of queries respectively.
The next line contains N space-separated integers denoting the array elements.

Each of the next M lines contains a single integer - p.

-----Output-----
Output a single integer corresponding to the maximum element in the pth subarray.

-----Constraints-----
- 1 ≤ Ai ≤ 109
- 1 ≤ p ≤ N+1C2

user: Chef is frustrated in this lockown. So to overcome this he plans to travel various mountains.
He is very strange so he sets some conditions for $each$ Type 2 query(mentioned below) (i.e. $1$ $i$) : 
- Let Chef has travelled till $ith$ mountain from left to right.
- He does not like to travel the mountain with the height ,of which he has travelled till now. More formally, 
Let the height of peak on which he is standing is $a_{i}$ then he can only go to the peak of height $a_{j}$ 
which is greater than $a_{i}$ and nearest to $ith$ mountain such that there should be no other peak of same height $a_{j}$ till $a_{i}$(height of $ith$ mountain) .

-----Input format:-----
- 
The first line contains an integer $T$ denoting the number of test cases.
- 
The second line of  consist of a integer $N$ and $Q$ .
- 
The third line contains $N$ not necessarily distinct positive integers $a_{0},a_{1}, . . .,a_{n-1}$ denoting the height of 
$N$ mountains.
- 
Then next $Q$ lines follows where each line consisting of $either$ of $2$ types of queries:
Type 1:  $0$ $A$ $B$ i.e. $a_{A} = B$ (where height of $Ath$ mountain will be updated to $B$) 
Type 2:  $1$ $A$ i.e. you have to answer $a_k$ which is greater than $a_{A}$ and nearest to $Ath$ mountain such that there should be no other peak of same height $a_{k}$ till $a_{A}$(height of $Ath$ mountain) .

-----Output format:-----
- For every query of Type 2 there should be an integer $a_{k}$ on next  line for the updated array , If no such $a_{k}$ exists then $a_{k}$= $-1$ , as query of type 1 will have no output . 

-----Constraints:-----
- $1\leq T \leq 10^2$
- $1 \leq N,Q \leq 10^4$
- $0\leq a_{i} \leq 10^6$
- $0\leq B \leq 10^6$

user: Indian National Olympiad in Informatics 2013
Calvin wakes up early one morning and finds that all his friends in the hostel are asleep. To amuse himself, he decides to play the following game : he draws a sequence of N squares on the ground, numbered 1 to N, and writes an integer in each square. He starts at square k (1 ≤ k ≤ N). The game consists of one forward phase followed by one backward phase.
- In the forward phase, Calvin makes zero or more moves of the following type : if his current position is p, he can jump to p+1 or p+2 as long as he stays within the N squares.
- In the backward phase, Calvin makes zero or more moves of the following type : if his current position is p, he can jump to p−1 or p−2 as long as he stays within the N squares.
He plays such that he finally ends up at square 1, and then he stops. He starts with a score of 0, and each time he jumps from square i to square j, he adds the integer written in square j to his score. Find the maximum score Calvin can obtain by playing this game. Recall that Calvin must start at square k and end at square 1. The integer on the square where he starts is not included in his score.
For example, suppose N = 5 and the numbers in squares are 5, 3, −2, 1, 1. If k = 2, Calvin starts on the second square. He can make a forward move to square 4, another to square 5, a backward move to square 4, another to square 2, and another to square 1. His total score is 1+1+1+3+5 = 11. You can check that this is the maximum score possible.

-----Input format-----
• Line 1 : Two space-separated integers, N and k, with 1 ≤ k ≤ N.
• Line 2 : A space-separated sequence of N integers, the numbers in squares 1, 2 . . . , N .

-----Output format-----
A single line with a single integer, the maximum score Calvin can obtain by playing the game.

-----Test Data-----
The testdata is grouped into two subtasks with the following constraints on the inputs.
• Subtask 1 [30 points] : 1 ≤ N ≤ 3000.
• Subtask 2 [70 points] : 1 ≤ N ≤ 106.
In all subtasks, the number in each square is between −1000 and 1000 inclusive.

Here is the sample input and output corresponding to the example above.

user: DevuLand is a very strange place. There are n villages in it. Some of the villages are occupied by dinosaurs while the remaining ones by villagers.
	You are given the information of DevuLand 
	by an array D of size n. If D[i] is non-negative, it means that there are D[i] villagers in that village. 
	Otherwise, it means that are -D[i] 
	dinosaurs in that village.

	It is also guaranteed that total number of villagers in DevuLand is equal to total number of dinosaurs.

Once dinosaurs got very hungry and started eating villagers. Frightened villagers gathered immediately and met their Sarpanch Deviji. Deviji, being a very daring and negotiable person, met to the head
of dinosaurs. Soon both parties called a truce. It was decided that the villagers will provide laddus to 
the dinosaurs. So everyday, each villager will take exactly one laddu to one of the dinosaurs in such a way that no dinosaur remains hungry (note that this is possible because number of villagers is the same as the number of dinosaurs).

Actually, carrying laddus is a quite a tough job. Villagers have to use a bullock cart for that. It takes one unit of grass a bullock to 
carry a cart with 1 laddu for 1 kilometre. Laddus used to be very heavy in DevuLand, so a bullock cart can not carry more than one laddu.

It is also given distance between village indexed i and j is |j - i| (the absolute value) kilometres.

Now villagers sat down and found a strategy to feed laddus to dinosaurs so that they need to buy the least amount of grass from the nearby market. 
They are not very good in 
calculations, please find out what is the minimum number of units of grass they need to buy.

-----Input-----

First line of the input contains an integer T denoting number of test cases.

For each test case, there are two lines. 

First line contains a single integer denoting n: number of villages. 

Second line contains n space separated integers denoting the array D.

-----Output-----

For each test case, print a single line containing the integer corresponding to answer of the problem.

-----Constraints-----

-  1 ≤ T ≤ 10^5 
-  1 ≤ n ≤ 10^5 
-  -10^4 ≤ D[i] ≤ 10^4 
-  Sum of n over all the test cases will be ≤ 10^6 
-  It is guaranteed that sum of D[i] is zero for a single test case which ensures that there are equal number of villagers and dinosaurs.

user: Harsh, like usual, started studying 6 months before for his end semester examinations. He was going to complete his 8th revision of the whole syllabus, when suddenly Pranav showed up in his room with the last year's question paper for their algorithms course. This paper contains a problem which both of them couldn't solve. Frustrated he asked you for help. But you declined him and instead try to do this problem instead:
You are given an array $A_1,A_2,\dots,A_N$, a positive integer $K$, and a function $F(x)=\displaystyle\sum_{i=1}^{N}{\left|{\left({x-A_i}\right)^K}\right|}$. Find the smallest integer $x$ such that $F(x)$ is minimum.Input
- The first line contains two space-seperated integers , $N$ and $K$
- The second line contains $N$ space-seperated integers $A_1,A_2,\dots,A_N$. Output
In the first and only line print the smallest integer $x$ such that $F(x)$ is minimumConstraints

Explanation 1
$F(6) = \displaystyle\sum_{i=1}^{N}{\left|{\left({6-A_i}\right)^K}\right|} \\ F(6) = \left|{\left({6-6}\right)^1}\right| + \left|{\left({6-1}\right)^1}\right| + \left|{\left({6-7}\right)^1}\right| \\ F(6)  = 0 + 5+ 1 \\ F(6)  = 6 $

$F(4) = \displaystyle\sum_{i=1}^{N}{\left|{\left({4-A_i}\right)^K}\right|} \\F(4) = \left|{\left({4-6}\right)^3}\right| + \left|{\left({4-1}\right)^3}\right| + \left|{\left({4-7}\right)^3}\right| \\F(4) = 8 + 27 + 27 \\F(4) = 62 $
Here $62$ is the minumum value for $F(x)$ for any integer value of $x$.
user: Tzuyu gave Nayeon a strip of $N$ cells (numbered $1$ through $N$) for her birthday. This strip is described by a sequence $A_1, A_2, \ldots, A_N$, where for each valid $i$, the $i$-th cell is blocked if $A_i = 1$ or free if $A_i = 0$. Tzuyu and Nayeon are going to use it to play a game with the following rules:
- The players alternate turns; Nayeon plays first.
- Initially, both players are outside of the strip. However, note that afterwards during the game, their positions are always different.
- In each turn, the current player should choose a free cell and move there. Afterwards, this cell becomes blocked and the players cannot move to it again.
- If it is the current player's first turn, she may move to any free cell.
- Otherwise, she may only move to one of the left and right adjacent cells, i.e. from a cell $c$, the current player may only move to the cell $c-1$ or $c+1$ (if it is free).
- If a player is unable to move to a free cell during her turn, this player loses the game.
Nayeon and Tzuyu are very smart, so they both play optimally. Since it is Nayeon's birthday, she wants to know if she can beat Tzuyu. Find out who wins.

-----Input-----
- The first line of the input contains a single integer $T$ denoting the number of test cases. The description of $T$ test cases follows.
- The first line of each test case contains a single integer $N$.
- The second line contains $N$ space-separated integers $A_1, A_2, \ldots, A_N$.

-----Output-----
For each test case, print a single line containing the string "Yes" if Nayeon wins the game or "No" if Tzuyu wins (without quotes).

-----Constraints-----
- $1 \le T \le 40,000$
- $2 \le N \le 3\cdot 10^5$
- $0 \le A_i \le 1$ for each valid $i$
- $A_1 = A_N = 1$
- the sum of $N$ over all test cases does not exceed $10^6$

-----Example Output-----
Yes
No
Yes
No

-----Explanation-----
Example case 1: Since both Nayeon and Tzuyu play optimally, Nayeon can start e.g. by moving to cell $4$, which then becomes blocked. Tzuyu has to pick either the cell $3$ or the cell $5$, which also becomes blocked. Nayeon is then left with only one empty cell next to cell $4$ (the one Tzuyu did not pick); after she moves there, Tzuyu is unable to move, so she loses the game.
Example case 2: Regardless of what cell Nayeon moves to at the start, Tzuyu will always be able to beat her.

user: This is another problem about Indraneel's library. His library has one long shelf. His books are numbered and he identifies the books by their number. Each book has a distinct number.
He has lost many books, since many of his friends borrow his books and never bother to return them. He does not want to lose any more books and has decided to keep a record of all books that he lends to his friends. To make the task of borrowing a book a little difficult, he has given the following instructions to his friends: when they borrow a book, they must record in a register its position from the left among the books currently on the shelf.
Suppose there are $5$ books in the library and they are arranged as follows:
261421532614215326 \quad 1 \quad 42 \quad 15 \quad 3
If someone walks in and borrows the book $42$, then he will record $3$ in the register because this book is the third from the left on the shelf. Now the shelf looks like this:
26115326115326 \quad 1 \quad 15 \quad 3
If the next person borrow the book $3$, he writes down $4$ in the register since this is currently the fourth book from the left on the shelf, and so on.
Indraneel knows the initial arrangement of the books in his library at the time that he introduced the register system. After a while he examines his register and would like to know which books have been borrowed. Your task is to write a program to help Indraneel solve this problem.

-----Input:-----
The first line of the input contains a single integer $M$ indicating the number of books in Indraneel's library. The next line contains $M$ distinct positive integers describing the sequence in which the books are arranged on the library shelf. The third line of input contains a single integer $N$ indicating the number of entries in the register. This, in turn, is followed by $N$ lines (lines $4$ to $N+3$), each containing one positive integer. The integer on line $3+i$ indicates the position from left of the book ith book borrowed. (You may assume that the number on line $3+i$ is at most $M-i+1$.)

-----Output:-----
$N$ lines with one positive integer on each line. The number on line $i$ is the book borrowed by the ith borrower.

-----Constraints:-----
- $1 \leq M \leq 1000000$.
- $1 \leq N \leq 4000$.

user: Amit is going on a date and he wants to gift his date an array of positive numbers. But he is running short on money. He already has an array of numbers in design. Cost of an array of numbers is the sum of elements in it. But he wants to minimize the cost of making it. 
So he does the following number of operations one by one for any number of times:
He chooses two adjacent elements ,replace them by one element with value = XOR of the two numbers. This operation reduces length of array (and elements are re-numerated accordingly)
Find the minimum amount of money that Amit needs to spend to gift his date.
