For a string to be palindrome the string should be equal to its reverse string. Therefore, we have to first reverse the string and then check the equality of that string with the original string.

First, i++ and j--pass the values of i and j with the post increment/decrement applied as a side effect after the next call to palindrome has already been made. Instead you need: return palindrome (c, i + 1, j - 1); Next, what happens if chaine has an even number of characters? i never equals j.You …
WebJun 11, 2024 · Approach 3 (Using stack) For Palindrome Linked List: A simple solution is to use a stack of list nodes. This mainly involves three steps.Traverse the given list from head to tail and push every visited node to stack.Traverse the list again. For every visited node, pop a node from the stack and compare data of popped nodes with currently visited ... WebFeb 20, 2024 · The idea is to take 2 pointers pointing at the first character and the other at the end character and check if both characters are equal until we reach the middle of the string. If a mismatch happens between any comparison we can then say that the given string is not a palindrome. As this is a recursive solution we know there are 3 parts of a ...
