Palindromex Codeforces Round 1096 (Div. 3) Greedy Solution with Dry Run and Detailed Explanation

In this video, you’ll learn:
How to think about palindromic subarrays efficiently
Why focusing around occurrences of 0 is important
How expanding around centers helps detect valid palindromes
How to compute MEX quickly for subarrays
How to combine all observations into an optimal solution

We also walk through the full C++ implementation and explain the logic behind each part so you don’t just memorize, but actually understand the approach.

This problem is a great example of combining two powerful ideas: palindrome expansion and MEX properties. Perfect for sharpening your problem-solving skills for contests like Codeforces, LeetCode, and more.

If you’re preparing for competitive programming or interviews, this one is definitely worth mastering.
