Binary Tree - 75: Connect Nodes at same Level with 'next' pointer
Source Code:https://thecodingsimplified.com/conne... Solution - 1: We do level order traversal & maintain a previous node At starting of every level, we set previous to null While traversing a npde, we point next of previous to current node Time Complexity: O(n) Space Complexity: O(n) Solution - 2: We traverse the binary tree in pre-order manner We keep on adding the next pointer for a level Time Complexity: O(n) Space Complexity: O(1) Do Watch video for more info CHECK OUT CODING SIMPLIFIED / codingsimplified ★☆★ VIEW THE BLOG POST: ★☆★ http://thecodingsimplified.com I started my YouTube channel, Coding Simplified, during Dec of 2015.
