Given a string S, find the longest palindromic substring in S. Substring of string S: S[ i . . . . j ] where 0 ≤ i ≤ j < len(S). Palindrome string: A string which reads the same backwards. More formally, S is palindrome if reverse(S) = S. Incase of conflict, return the substring which occurs first ( with the least starting index ).
NOTE: Required Time Complexity O(n2).
Input:
The first line of input consists number of the testcases. The following T lines consist of a string each.
Output:
In each separate line print the longest palindrome of the string given in the respective test case.
Constraints:
1 ≤ T ≤ 100
1 ≤ Str Length ≤ 104
Example:
Input:
1
aaaabbaa
Output:
aabbaa
Explanation:
Testcase 1: The longest palindrome string present in the given string is "aabbaa".
