In this video, we solve LeetCode: Maximum K to Sort a Permutation, a problem that combines bitwise operations, permutation analysis, and greedy insight to find the best constraint that still allows sorting via restricted swaps.
📌 In this video, you’ll learn:
• How to interpret a permutation and when it’s considered sorted
• Using bitwise AND to determine the maximum allowed value k
• Why the common bits of all misplaced elements determine swap feasibility
• Efficiently computing the answer in O(n) time
• Time & space complexity analysis
This problem is great for strengthening your understanding of bit manipulation, permutation invariants, and greedy strategies, and it’s highly useful for interview preparation and competitive programming practice.
