WebFeb 9, 2024 · The length of the longest palindromic substring is simply the maximum value in the P array. The P array stores the length of the longest palindromic substring centered at each character of the processed string. From the P array, we can see that the length of the longest palindromic substring is 3, which is centered at index 7. WebCount the number of substrings of a string, such that any of their permutations is a palindrome. So, for aab, the answer is 5 - a, a, b, aa and aab (which can be permuted to form aba ).
