In today’s LeetCode Problem of the Day, we solve
3719. Longest Balanced Subarray I (Medium) 🚀
A subarray is called balanced when the number of distinct even elements is equal to the number of distinct odd elements.
👉 We start by discussing why a naive brute-force approach is inefficient
👉 Then we move to an optimized O(n²) brute-force solution using HashSets
👉 We also explain why a sliding window approach fails for this problem
This solution is:
• ✅ Easy to understand
• ✅ Interview-friendly
• ✅ Perfect for daily LeetCode practice
Solution: https://leetcode.com/problems/longest...
📌 Time Complexity: O(n²)
📌 Space Complexity: O(n)
