Graph: Depth First Search Bottom up for O(N) Solution 110. Balanced Binary Tree. Given a binary tree, determine if it is height-balanced. For this problem, a height-balanced binary tree is defined as a binary tree in which the depth of the two subtrees of every node never differ by more than 1. Naive O(N^2) Solution is:

In Depth-First Search (DFS), we aim to finish one branch before looking at other branches. A good example of DFS is the following problem (LeetCode Link): Given the root of a binary tree, return its maximum depth.
21 kwi 2020 · In today’s tutorial, we are going to discover a DFS pattern that will be used to solve some of the important tree and graph questions for your next Tech Giant Interview! We will solve some Medium and Hard Leetcode problems using the same common technique.
Overview. In Depth-First Search (DFS), we aim to finish one branch before looking at other branches. A good example of DFS is the following problem (LeetCode Link): Given the root of a binary tree, return its maximum depth. A binary tree's maximum depth is the number of nodes along the longest path from the root node down to the farthest leaf node.
Given a connected undirected graph represented by an adjacency list adj, which is a vector of vectors where each adj[i] represents the list of vertices connected to vertex i. Perform a Depth First Traversal (DFS) starting from ver.
