and then compute the number of palindromic substrings from i+1 to strlen(N)-1 in a suffix sum array. We can then sum the products of prefix[i]*suffix[i+1] and somehow account for overcounting to get our answer. My main issue is finding the number of palindromic...
The Number of Palindromes Problem Description Now, you are given a string S. We want to know how many distinct substring of S which is palindrome. Input The first line of the input contains a single integer T(T<=20), which indicates number of test cases. Each test case consists of a ...
each query is described by two integersli, ri(1 ≤ li ≤ ri ≤ |s|). The answer to the query is the number of substrings of strings[li...ri], which are palindromes.
The answer to the query is the number of substrings of string s[s[ lili ... riri ]] , which are palindromes. String s[l... r]s[l... r]=slslsl+1sl+1... sr sr(1<=l<=r<=∣s∣) is a substring of string s=s1s2... s|s|s=s1s2... s|s| . String tt is called ...

A palindrome is a word, phrase, number, or other sequence of characters that reads the same backward as forward. In other words, it remains unchanged when its characters are reversed. For example, words like "radar," "level," and "madam" are palindromes, as well as phrases like "Able ...
