Steps for Level order traversal algorithm: Create empty queue and pust root node to it. Do the following when queue is not empty.
Trees can also be traversed in level-order, where we visit every node on a ...
Given the root of a binary tree, return the level order traversal of its nodes' values. (i.e., from left to right, level by level). Example 1: Input: root = [3,9,20,null,null ...

We can print all nodes present in a level by modifying the preorder traversal on the tree. This is demonstrated below in C++, Java, and Python: C++; Java; Python ...
