Check if a string is a palindrome

Question

I have a string as input and have to break the string in two substrings. If the left substring equals the right substring then do some logic.

How can I do this?

Answer 1

This C# method will check for even and odd length palindrome string (Recursive Approach):

public static bool IsPalindromeResursive(int rightIndex, int leftIndex, char[] inputString)
{
    if (rightIndex == leftIndex || rightIndex < leftIndex)
        return true;
    if (inputString[rightIndex] == inputString[leftIndex])
        return IsPalindromeResursive(--rightIndex, ++leftIndex, inputString);
    else
        return false;            
}
