Given a complete binary tree, count the number of nodes. Note: Definition of a complete binary tree fromWikipedia: In a complete binary tree every level, except possibly the last, is completely filled, and all nodes in the last level are as far left as possible. It can have between 1 a...

Can you solve this real interview question? Count Good Nodes in Binary Tree - Given a binary tree root, a node X in the tree is named good if in the path from root to X there are no nodes with a value greater than X. Return the number of good nodes in t
Give a definition of the function nodeCount, that returns the number of nodes in a binary tree.Counting All the Nodes in a Binary TreeA binary tree is a special type of non-linear data structure where every node may contain a single child node, two child n...

The time complexity for iterative approach is O(n), where n is the number of nodes in the binary tree. This is because each node in the tree is visited to determine whether it is a leaf node or not. The space complexity is O(w) where w is the maximum width in the binary tree. ...
