WebThe level order traversal is a basic algorithm used extensively in various tree problems, which uses a queue and adds the nodes present at each level. In the case of a binary tree, we will add the children of all the nodes in the queue and visit the nodes in it. Also, pop the nodes once visited. WebPostorder traversal can also be performed using a non-recursive or iterative algorithm. Some sources solve this problem (poorly, in my opinion) by using two different stacks.
