Solution: Valid Palindrome II

Problem Statement

Given string s, determine whether it's possible to make a given string palindrome by removing at most one character.

A palindrome is a word or phrase that reads the same backward as forward.

Examples

  1. Example 1:

    • Input: "racecar"
    • Expected Output: true
    • Justification: The string is already a palindrome, so no removals are needed.

  2. Example 2:

    • Input: "abeccdeba"
    • Expected Output: true
    • Justification: Removing the character 'd' forms the palindrome "abccba".

  3. Example 3:

    • Input: "abcdef"
