Given a binary tree, how would you set the keys/values of all the nodes and their child pointers to null. No language restriction. Do it iteratively in O(N) time with O(1) space complexity where N is the number of nodes in the tree. Other Details: - Tree is just a regular Binary Tree and doesn't have the BST property. - It is not guaranteed to be balanced. - You may do whatever you want to the tree however, you must ensure that all the nodes in the tree and their left/right pointers are set to null.
