First non-Palindrome

Problem code: NONPALIN

  • Submit
  • All submissions

All submissions for this problem are available.

For the given string S of length N you need to find for each L from 1 to N the first non-palindrome substring of S that has length L. That is, for each L from 1 to N you need to find the smallest positive integer K <= N - L + 1 such that the string S[K, K + L - 1] is not a palindrome. Denote this number by K(L). Here S[i, j] stands for the substring of S composed of its characters in positions i, i + 1, ..., j. Characters of S are numbered from 1 to N. If for some L there is no such K set K(L) = 0. After you find all numbers K(1), K(2), ..., K(N) output the following sum

100007N - 1 * K(1) + 100007N - 2 * K(2) + ... + 100007 * K(N - 1) + K(N)

modulo 264.

Remark. The string is called a palindrome if it coincides with its reverse. So abacaba and abba are palindromes but codechef and abbc are not.

Input

The first line contains a single integer T, the number of test cases. T test cases follow. The only line of each test case contains a non-empty string composed only of lowercase letters of the English alphabet.

Output

For each test case, output a single line containing the corresponding sum constructed by numbers K(1), K(2), ..., K(N) as mentioned in the problem statement modulo 264.

Constraints

1 <= T <= 20
1 <= length of S <= 100000

Example

Input:
4
abacaba
abba
codechef
aaaa

Output:
12789123637940213592
10001500056
18134494634143926857
0

Explanation

Actual values of K(1), K(2), ..., K(N) in the tests are:
abacaba: {0, 1, 2, 1, 1, 1, 0}
abba: {0, 1, 1, 0}
codechef: {0, 1, 1, 1, 1, 1, 1, 1}
aaaa: {0, 0, 0, 0}

HELP

Program should read from standard input and write to standard output.

After you submit a solution you can see your results by clicking on the [My Submissions] tab on the problem page. Below are the possible results:

  • Accepted Your program ran successfully and gave a correct answer. If there is a score for the problem, this will be displayed in parenthesis next to the checkmark.
  • Time Limit Exceeded Your program was compiled successfully, but it didn't stop before time limit. Try optimizing your approach.
  • Wrong Answer Your program compiled and ran succesfully but the output did not match the expected output.
  • Runtime Error Your code compiled and ran but encountered an error. The most common reasons are using too much memory or dividing by zero. For the specific error codes see the help section.
  • Compilation Error Your code was unable to compile. When you see this icon, click on it for more information.
