Master Unique Paths in 7 Minutes ⚡ Recursion + Memoization (Blind 75 #25)

In this video, we break down the Unique Paths problem (LeetCode Blind 75 #25) step by step — one of the most important Dynamic Programming problems for coding interviews.

We start with a simple recursion approach to build intuition and then optimise it using Memoisation (Top-Down DP) so you can understand how interviewers expect you to think.

If you're preparing for FAANG / product-based companies, this problem is a must-do for mastering DP patterns.

🚀 What you'll learn:

• How to think in terms of recursion
• Identifying overlapping subproblems
• Converting recursion → memoization
• Writing clean DP code
