Recursion Basics + Call Stack Explained (Visual Dry Run + Common Mistakes)

Recursion becomes easy once you understand what happens behind the scenes in the call stack. In this video, you’ll learn recursion from zero, see how function calls are stored and returned, and do a full dry run so you can write recursion confidently in DSA problems. ✅ What you’ll learn: What recursion is (in the simplest terms) Call stack explained step-by-step (how calls are pushed/popped) How to write recursion properly: base case + recursive call + return Dry run of recursion with a real example (like factorial / sum of n numbers) Common recursion mistakes (infinite recursion, wrong base case, stack overflow) How to think recursively like an interviewer expects 🎯 By the end, you’ll be able to trace recursion correctly and solve beginner recursion problems confidently.
