In this video, we break down the Pascal’s Triangle problem step by step using the mathematical nCr formula and cover all the 3 commonly asked variations in coding interviews.
We’ll cover:
• Type 1: Finding a specific element in Pascal’s Triangle
• Type 2: Generating a particular row efficiently
• Type 3: Building the complete Pascal’s Triangle
• Using nCr for an optimal mathematical approach
• Intuition + dry run for better understanding
• Time & space complexity explanation
This problem is frequently asked in coding interviews and helps build strong fundamentals in mathematics-based problem solving, patterns, and combinatorics.
Perfect for:
• DSA preparation
• Coding interviews
• LeetCode practice
• Learning mathematical optimization techniques
