WebThese properties are clearly visible in your binary search tree so the answer is true. B. The maximum number of nodes on level i of a binary tree is given by the formula: 2i −1. This formula works for any level i, where i >= 1. The intuition behind this formula is that at level 1, there is only one node (the root).

WebHere are some of the steps for tree traversal : Step 1: First we will print the root element which is 10 in above example. Step 2: Traverse the left subtree recursively. The only node on left subtree is 20 . So print it and move to the right subtree of root. Step 3: 30 is the root of right sub-tree , therefore , print it and move to its left. WebIncrease the value of a i by X. Find the sum of a i on the path from u to v for 2 nodes u and v. First, we flatten the tree using a preorder traversal. Let the time we enter node i be t i n i and the time we exit it be t o u t i. Additionally, let b be an array/Fenwick tree of size 2 N. If you're familiar with LCA, you'll know that node u is an ...
