WebGiven a string s, return the number of palindromic substrings in it. A string is a palindrome when it reads the same backward as forward. A substring is a contiguous sequence of characters within the string. Example 1: Input: s = "abc" Output: 3 Explanation: Three palindromic strings: "a", "b", "c". Example 2: 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 ). I feel this is dynamic programming, but I can't find what kind of relations the subproblems might have.
