4Welcome to srkcodes, your trusted channel for Telugu coding tutorials, GeeksforGeeks solutions, and Python programming for interviews! In today’s video, we’ll solve the Longest Palindromic Substring problem from GeeksforGeeks, an important challenge for DSA preparation and coding interviews.
🔍 What You’ll Learn:
1️ ⃣ Brute Force Approach (O(N³)):
Check all possible substrings.
Verify if each substring is a palindrome.
Keep track of the longest palindrome.
2️ ⃣ Optimal Approach (Expand Around Center) (O(N²)):
Expand from each character as a center.
Handle odd-length and even-length palindromes.
Efficiently find the longest palindrome in linear time.
