Distance between two nodes in binary tree
WebOct 18, 2024 · Code in Python """ Given a binary tree, find the horizontal distance between 2 nodes at the same level, also counting the position where the node is not present. """ # binary tree node class Node: # … WebGiven a binary tree and two node values your task is to find the minimum distance between them. Please Note that a and b are not always leaf node. Input: 1 / \ 2 3 a = 2, b = 3 Output: 2 Explanation: The tree formed is: 1 / \ 2 3 We need the distance between 2 and 3. Being at node 2, we need to take two steps ahead in order to reach node 3.

WebFeb 23, 2024 · Explanation of Sample Input 1: For the first test case, the distance between node 7 and node 2 will be 4 as there are 4 edges between these two given nodes, i.e. 7 -> 4, 4 -> 6, 6 -> 5, and 5 -> 2. For the second test case, the answer will be -1 as node 4 is not present in the binary tree. WebJun 19, 2012 · 0. This must be a recursive algorithm. dis (tree, x, y) <--function call x & y are nodes. each recursive calls returns (dx, dy, dxy) dx is depth of x dy is depth of y dxy is distance from each other. I'm thinking using lowest common ancestor, but that doesn't suit this format (no global variables). algorithm. recursion.
WebJun 21, 2024 · Follow the steps below to solve the problem: Initialize a queue, say Q, to store the nodes at each level of the tree. Initialize an array, say dist [], where dist [i] stores the distance from the root node to ith of the tree. Traverse the tree using BFS. For every ith node encountered, update dist [i] to the level of that node in the binary tree.
