Dustin, is the head of an Intelligence agency. He wants to send a secret message S$S$ to his colleague.The message is a single word consisting of only lowercase english letters but he decides to encrypt the message for security reasons. He makes a string M$M$ of length N$N$, such that after deleting a substring of non-zero length from M$M$, the remaining string is S$S$.
Calculate the number of all such possible strings he can form.

-----Input:-----
- First line will contain T$T$, number of testcases. Then the testcases follow.
- For each testcase the there is a single line which contains an integer, N$N$ and then a string S$S$.

-----Output:-----
For each testcase, output the number of possible strings modulo 109+7$10^9+7$.

-----Constraints-----
- 1≤T≤50$1 \leq T \leq 50$
- 1≤N≤1018$1 \leq N \leq 10^{18}$
- 1≤|S|≤105$1 \leq |S| \leq 10^5$
- S$S$ can contain only lowercase English letters.

-----Sample Input:-----
2

3 a

3 ab     

-----Sample Output:-----
1326

Given an array of n$n$ integers : A1,A2,...,An$ A_1, A_2,... , A_n$, find the longest size subsequence which satisfies the following property: The xor of adjacent integers in the subsequence must be non-decreasing.

-----Input:-----
- First line contains an integer n$n$, denoting the length of the array. 
- Second line will contain n$n$ space separated integers, denoting the elements of the array.

-----Constraints-----
- 1≤n≤103$1 \leq n \leq 10^3$

You have been recently hired as a developer in CodeChef. Your first mission is to implement a feature that will determine the number of submissions that were judged late in a contest.
There are $N$ submissions, numbered $1$ through $N$. For each valid $i$, the $i$-th submission was submitted at time $S_i$ and judged at time $J_i$ (in minutes). Submitting and judging both take zero time. Please determine how many submissions received their verdicts after a delay of more than $5$ minutes.

-----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 the input contains a single integer $N$.
- $N$ lines follow. For each valid $i$, the $i$-th of these lines contains two space-separated integers $S_i$ and $J_i$.

-----Output-----
For each test case, print a single line containing one integer — the number of submissions for which the judging was delayed by more than 5 minutes.

-----Constraints-----
- $1 \le T \le 100$
- $1 \le N \le 100$
- $1 \le S_i \le J_i \le 300$ for each valid $i$

-----Subtasks-----
Subtask #1 (100 points): original constraints

-----Example Input-----
1
5
1 3
4 4
4 10
1 11
2 7

-----Example Output-----
2

-----Explanation-----
Example case 1: The delays of the respective submissions are $2$ minutes, $0$ minutes, $6$ minutes, $10$ minutes and $5$ minutes. Only submissions $3$ and $4$ are delayed by more than $5$ minutes, hence the answer is $2$.

=====Function Descriptions=====
re.findall()

The expression re.findall() returns all the non-overlapping matches of patterns in a string as a list of strings.
Code

>>> import re
>>> re.findall(r'\w','http://www.hackerrank.com/')
['h', 't', 't', 'p', 'w', 'w', 'w', 'h', 'a', 'c', 'k', 'e', 'r', 'r', 'a', 'n', 'k', 'c', 'o', 'm']

re.finditer()

The expression re.finditer() returns an iterator yielding MatchObject instances over all non-overlapping matches for the re pattern in the string.
Code

>>> import re
>>> re.finditer(r'\w','http://www.hackerrank.com/')
<callable-iterator object at 0x0266C790>
>>> map(lambda x: x.group(),re.finditer(r'\w','http://www.hackerrank.com/'))
['h', 't', 't', 'p', 'w', 'w', 'w', 'h', 'a', 'c', 'k', 'e', 'r', 'r', 'a', 'n', 'k', 'c', 'o', 'm']

=====Problem Statement=====
You are given a string S. It consists of alphanumeric characters, spaces and symbols(+,-).
Your task is to find all the substrings of S that contains 2 or more vowels.
Also, these substrings must lie in between 2 consonants and should contain vowels only.

Note :
Vowels are defined as: AEIOU and aeiou.
Consonants are defined as: QWRTYPSDFGHJKLZXCVBNM and qwrtypsdfghjklzxcvbnm.

=====Input Format=====
A single line of input containing string S.

=====Constraints=====
0<len(S)<100

=====Output Format=====
Print the matched substrings in their order of occurrence on separate lines.
If no match is found, print -1.

In a bizarre game of chess ,knight was so drunk, that instead of his usual move he started walking straight. In every move Knight jumps on 2n steps forward (n is number of block that he had travelled so far from starting) but after that he has to take either 1 step forward or backward.
Now the Knight needs to get to position X so King (i.e. You) needs to decide the order of his backward or forward step in such a way that he can reach its destination in minimum number of steps. Remember he always travels in a straight line and the length of the board is infinite.

-----Input-----
The first line of the input contains an integer T denoting the number of test cases, for each test case enter value X ( i.e. destination)
Note : initially knight is at n = 1.

-----Output-----
For each test case the output should be string of numbers 1 & 2 where 1 denotes backward step and 2 denote the forward step 
Note : for no solution print 0.

-----Constraints-----
- 1 ≤ T ≤ 100
- 1 ≤ X ≤ 10^10

-----Example-----
Input:
2
17
10
Output:
2111
0

-----Explanation-----
Case 1 : starting from  n = 1 , knight moves to n = 3 ('2') , 5 ('1') , 9 ('1') , 17 ('1') i.e. string printed is 2 1 1 1
Case 2 : no solution is possible

So the Chef has become health conscious and is now lifting weights at the gym. But its his first time so the trainer gives him a simple job to do. 

He has been given a weight lifting rod and N heavy weights, each weighing 20, 21, .... , 2n-1. He has to stick each of the "N" weights on the rod, one after another, in such a way that the right side is never heavier than the left side. At each step he chooses one of the weights that has not yet been fixed on the rod, and fix it on either the left side of the rod or the right, until all of the weights have been placed.

Now help the chef and find out, in how many ways the chef can accomplish this?

-----Input-----
First line of input contains an integer T, the number of test cases. Then T test cases follow. Each line of test case contains one integer, N denoting the number of weights

-----Output-----
The output contains T lines, each containing an integer denoting all possible combinations

-----Example-----
Input:

Given an integer N, Chef wants to find the smallest positive integer M such that the bitwise XOR of M and M+1 is N. If no such M exists output -1.

-----Input-----
The first line of input contain an integer T denoting the number of test cases. Each of the following T lines contains an integer N for that test case.

-----Output-----
For each test case, output a single line containing the number M or -1 as described above.

-----Constraints-----
- 1 ≤ T ≤ 5000
- 1 ≤ N ≤ 230

-----Example-----
Input:
1
3

Output:
1

-----Explanation-----First Example :  M desired in the problem would be 1. As bitwise XOR of 1 and 2 is equal to 3.

You get an array of numbers, return the sum of all of the positives ones.

Example `[1,-4,7,12]` => `1 + 7 + 12 = 20`

Note: if there is nothing to sum, the sum is default to `0`.

One of Chef's friends offered him a deal: during $D$ days, they are going to exchange money. For each $i$ ($1 \le i \le D$), on the $i$-th day, Chef's friend would give Chef $A$ rupees, while Chef would give his friend $2^{i-1}$ rupees ($1$ rupee on day $1$, $2$ rupees on day $2$, $4$ rupees on day $3$, and so on). Chef's profit from the deal is the total number of rupees he received from his friend minus the total number of rupees he gave his friend.
Chef decided to ask for your advice before accepting the deal. You want to help him by telling him two numbers $D_1$ and $D_2$, where $D_1$ is the maximum value of $D$ such that Chef should accept the deal, i.e. his profit from the deal is positive if $D = D_1$, and $D_2$ is the value of $D$ that leads to the maximum possible profit for Chef. If there are multiple values of $D$ that lead to the maximum profit, $D_2$ is the smallest of these values.

-----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 and only line of each test case contains a single integer $A$.

-----Output-----
For each test case, print a single line containing two space-separated integers $D_1$ and $D_2$.

-----Constraints-----
- $1 \le T \le 100,000$
- $5 \le A \le 10^9$

-----Subtasks-----
Subtask #1 (100 points): original constraints

-----Example Input-----
