Breadth-First Search pattern
Maximum Width of Binary Tree
Given the root of a binary tree, return the maximum width across all levels, where a level's width is the distance between its leftmost and rightmost non-null nodes counting the null positions between them as if the tree were a complete binary tree. Watch it run step by step, then write your own pseudocode and get it checked by AI.
