WebAug 29, 2015 · The solution seems n^2 but isPalindrome is executed only once. Due to the problem specification there exists only one valid solution (and it always exists). Therefore I process the string as in a normal palindrome check, if it fails I try to figure out if the removal of the left index helps or not. If it helps the left index is the answer, if ... WebThere will always be at least one palindrome which can be formed with the letters of the given string. Input: The first line contains the number of test cases T. Each of the next T lines contains a string each. Output: Output T lines containing the answer for the corresponding test case. Print the answer correct to 4 decimal places. WebDec 24, 2024 · In the PalindromeIndex function, I first check if a string is a palidrome then return -1, else I will loop through the string, try to remove each letter to see if the remaining string is a palindrome. If it is, return the index right there; else, continue. If the loop finishes without returning any index, that means there is no result, I return -1. freight concepts tracking
