Given a binary tree, find the product of all the leaf nodes.
Input : 1 / \ 2 3 / \ / \ 4 5 6 7 \ 8 Output : product = 4 * 5 * 8 * 7 = 1120
The idea is to traverse the tree in any fashion and check if the node is the leaf node or not. If the node is the leaf node, multiply node data to a variable prod used to store the products of leaf nodes.
Following is the implementation of above approach.
Time Complexity : O(n), where n is the total number of nodes in the tree.
