LeetCode 75 C++ | Step-by-Step Solutions (LAN Academy) - LeetCode 1161 – Maximum Level Sum of a Binary Tree | Clean BFS Solution in C++

In this video we solve LeetCode 1161 – “Maximum Level Sum of a Binary Tree” step by step in C++. You’ll learn how to: • Traverse the tree level by level using BFS (queue) • Keep track of the sum on each level • Find the smallest level with the maximum sum • Reason about time and memory complexity This problem is part of my LeetCode 75 series in C++ – explained slowly, visually and logically so you really understand the ideas, not just copy code.
