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.

Didnt ask anything about me or my resume. They sent ma link to write the code. Asked me to write the code for finding the number of words in a string without using split and scanner. Then asked me to improve the code to accommodate corner case i.e if multiple spaces or null string etc. Asked me to write the test cases for the program.
