4085. Find Root of a Colored Tree | LeetCode Weekly Contest 524 | O(N) Optimal Approach

Welcome to ⁨@RealGuideBhai⁩ In this video, we solve "Find Root of a Colored Tree" from LeetCode Weekly Contest 524. We avoid the O(N^2) TLE trap and solve it in optimal O(N) time by using the strict (R - B - W) color sequence to convert the undirected tree into a directed graph. Timestamps: 00:00 - Problem Statement 02:39 - Problem Understanding 03:25 - Brute Force O(N^2) 04:50 - Optimal Approach 05:35 - Is multi Roots possible ?? 08:25 - Finding Single root 09:48 - Binary property 10:19 - Find next node 11:29 - Code Implementation 13:58 - Multi Roots ?? 15:22 - The Hidden Binary Tree Constraint 17:03 - Manual write vs Pre written ??
