Master Recursion in One Video | Stack, Rec. Tree & 3BHK Trick | LC 50, 231, 509 | DSA 360: EP 07

Master recursion from scratch with this powerful beginner-to-intermediate guide covering stack frames, base cases, and recursion trees in a clear and intuitive way. In this lecture, we break down how recursive calls work internally, how to visualize them using recursion trees, and how to avoid common mistakes. We also solve important LeetCode problems like Fibonacci Number (LC 509), Pow(x, n) (LC 50), and Power of Two (LC 231), along with smart tricks to identify and optimize recursive solutions. Perfect for DSA learners, coding interview preparation, and anyone looking to build strong problem-solving skills in recursion.
