🔥 LeetCode 119 Pascal’s Triangle II in C++ | Optimal O(n) Solution Explained

Hello everyone 👋 In this video, we solve LeetCode Problem #119 – Pascal’s Triangle II using an optimized mathematical approach in C++. Unlike Pascal’s Triangle (Problem 118), here we only need to generate a specific row instead of the entire triangle. To make the solution efficient, we use a formula-based approach that allows us to compute each element in a single pass. In this video, you will learn: Problem understanding Optimized O(n) approach Mathematical formula explanation Complete C++ code Step-by-step code walkthrough Time and space complexity This problem is very important for coding interviews and helps in understanding patterns and combinations. 💻 Language used: C++ ⏱ Time Complexity: O(n) 📦 Space Complexity: O(n) If you found this helpful, don’t forget to like 👍, share 🔁, and subscribe 🔔 for more coding and interview preparation videos. #leetcode #pascalstriangle #cpp #coding #dsa #interviewprep #programming
