3Sum Explained: Brute Force vs Optimal | Blind 75 Must-Know Interview Question

Hey everyone! 🚀 In this video, I solve the LeetCode Problem: 3Sum (15). I’ll walk you through the problem statement, discuss the brute force and optimized two-pointer approaches, and implement an efficient solution in C++. 🔹 Problem Statement: Given an array of integers, find all unique triplets that sum up to zero. 🔹 Approach: We’ll first analyze the brute force approach (O(N³)), then optimize it using the two-pointer technique (O(N²)) after sorting the array. 🔹 Time Complexity: ✅ Brute Force: O(N³) ✅ Optimized Approach: O(N²) 🔹 Code link: https://github.com/Code-Brothers01/DS... 🔥 Subscribe for daily LeetCode solutions! 💬 Drop your thoughts and alternative solutions in the comments! 🚀
