🔎 What is Recursion?
Recursion is a programming technique where a function calls itself directly or indirectly to solve a problem.
✨ Why Learn Recursion?
- Helps solve problems that can be broken into smaller sub-problems.
- Foundation for advanced algorithms like divide and conquer, dynamic programming, and tree traversals.
- Visualizing recursion improves understanding of function calls and call stack.
🌍 Real-Life Applications
- Mathematical computations like factorial, Fibonacci, combinations.
- Solving puzzles like Tower of Hanoi.
- Tree and graph algorithms, recursive sorting (Merge Sort, Quick Sort).
- Backtracking problems like maze solving, N-Queens problem.
