Make Palindrome

CodeChefRating 2391Open on judge ↗

Divyam is teaching his student Amit about palindromes. A palindrome is a word, phrase, number, or other sequence of characters which reads the same backward or forward. For example, the string “abcba” is a palindrome. After teaching about it, Divyam gave a puzzle for Amit to solve: Given a string S. Find the number of positions in S where we can insert a character to convert it into a palindrome.
