Find the maximum width of a binary tree using level-order or preorder traversal

geeksforgeeks.org

The maximum width of a binary tree is determined to be 4. This is the highest number of nodes found at any single level within the tree structure. This maximum width is achieved on the third level of the tree, which contains four nodes. Previous levels had fewer nodes: one on the first level and two on the second. The article presents two primary methods for calculating this maximum width: a level-order traversal (BFS) and a preorder traversal, both achieving O(n) time complexity.
