5. Let T be a proper binary tree with root r. Consider the following algorithm Algorithm traverse(r) Input: Root r of a proper binary tree. if r is a leaf then return 0 else ttraverse(left child of r) ?traverse(right child of r) return s+t+1 What does the algorithm do? (A) It computes the height of the tree. (B) It computes the number of nodes in the tree. (C) It computes the number of nodes in the tree plus 1. (D) It computes the number of leaves in the tree. (E) It computes the number of internal nodes in the tree
