Maximum Width of Binary Tree

Tags: python queue java

The problem statement, as given on LeetCode, asks us to find the maximum width of a binary tree. The width of a level is defined as the number of nodes at that level. The maximum width of the binary tree is the maximum width among all levels.


Code Walkthrough

Initialization: Start with the root node of the binary tree. Initialize a queue to hold nodes and their positions. Set a variable max_width to keep track of the maximum width seen so far (initially set to 0).

Breadth-First Search (BFS): Perform a BFS traversal of the binary tree. Begin with the root node and assign it a position of 0. Enqueue the root node along with its position into the queue.

While the Queue is not Empty:

Time Complexity

The time complexity is O(N), where N is the number of nodes in the binary tree. This is because both solutions traverse all nodes in the tree once using BFS.
