Two trees are isomorphic in the following 2 cases. 1. both trees are null; 2. a.neither tree is null; b.their roots' values are the same; c. either tree 1's left subtree is isomorphic with tree 2's left subtree and tree 1's right subtree is isomorphic with tree 2's right subtr...
1. Count the total number of nodes in given binary tree in O(n) time. 2. From bottom to top, for each node A, treat it as a root node and count the total number of nodes in this subtree recursively. 3. For each node A, check if there exists an edge that halves the given inp...
