Solving Leet code's 3Sum Question: Easy-to-Follow Coding Guide #code #leetcode #dsa

The 3Sum problem on LeetCode asks you to find all unique triplets in an array that sum up to zero. You're given an array of integers, and the goal is to return a list of unique triplets (a, b, c) where a + b + c equals zero. To solve this efficiently, you'll typically sort the array first. Then, using a combination of pointers and iteration, you'll traverse the array while checking for triplets that sum up to zero. It involves a bit of clever pointer movement to avoid duplicates and optimize the solution.
