Leetcode 3844: Longest Almost Palindromic Substring

Struggling with LeetCode 3842? In this video, we break down the "Almost Palindromic" problem using an intuitive Dynamic Programming approach. An "Almost Palindrome" is a string that can become a palindrome by removing at most one character. We'll walk through: The 2D DP table for standard palindromes. How to extend that logic to handle the "one-character-delete" rule. Complexity analysis O(n^2) time and space. Code Breakdown: Step 1: Pre-calculate isPalindrome[i][j] using interval DP. Step 2: Build isAlmostPalindrome[i][j] by checking if removing the head or tail results in a valid palindrome.
