5 Problems
Recursion solves problems by breaking them into smaller sub-problems. A recursive function calls itself with modified arguments until it reaches a base case. For example, to compute a factorial, the function multiplies the number by the factorial of the previous number until reaching 1. Recursion is effective for tasks like navigating trees or graphs but needs careful handling to avoid infinite loops and stack overflow. Properly defined base cases and managing function calls are crucial for effective recursion, which often leads to elegant and concise solutions.
