🚀 100 DAYS • 100 DSA PROBLEMS — 🔥 Day 15: Three Number Sum in Python | DSA Coding Challenge

🚀 *100 DAYS • 100 DSA PROBLEMS — DAY 15* 🔥 *Day 15: Three Number Sum in Python | DSA Coding Challenge* Can you find three numbers in an array that add up to a target sum? 🤔 Welcome to *Day 15 of my 100 Days 100 DSA Challenge!* Today, we're solving the famous *Three Number Sum (3Sum)* problem using Python and learning how sorting and the two-pointer technique can make our solution more efficient. 🧠 *Problem Statement:* Given an array of integers and a target sum, find all triplets whose elements add up to the target. 💻 *Example:* *Input:* ```python array = [12, 3, 1, 2, -6, 5, -8, 6] targetSum = 0 ``` *Output:* ```python [[-8, 2, 6], [-8, 3, 5], [-6, 1, 5]] ``` ✅ Each triplet contains three numbers that add up to `0`. 🎯 *What You'll Learn:* ✅ Understanding the Three Number Sum problem ✅ Sorting arrays in Python ✅ Using the Two Pointer technique ✅ Finding unique triplets ✅ Improving brute-force solutions ✅ Time and Space Complexity analysis ⚡ *Coding Interview Challenge:* Can you solve this problem more efficiently than checking every possible triplet? Try implementing the solution yourself before watching the complete walkthrough! 📅 *Challenge:* 100 Days 100 DSA 🔥 *Day:* 15/100 🐍 *Programming Language:* Python 🎯 *Goal:* Master DSA and prepare for coding interviews. If you're preparing for **FAANG/MAANG, product-based companies, or software engineering interviews**, join me as we solve one DSA problem every day for 100 days! 👍 Like the video if it helped you. 💬 Comment your approach or questions below. 🔔 Subscribe and follow the journey for daily DSA problems! #100Days100DSA #ThreeNumberSum #3Sum #Python #PythonDSA #DSA #TwoPointers #CodingChallenge #DataStructures #Algorithms #CodingInterview #ProblemSolving #LeetCode #LearnPython #FAANG #MAANG #SoftwareEngineer
