Recursion is a programming technique where a function calls itself to solve smaller instances of the same problem.
Recursion works on the concept of breaking a problem into smaller subproblems until a base condition is met.
void recursiveFunction() {
// Base condition
if (condition)
return;
// Recursive call
recursiveFunction();
}
int factorial(int n) {
if (n == 0)
return 1;
return n * factorial(n - 1);
}
Recursion provides an elegant solution for divide-and-conquer problems but must be used carefully to avoid memory issues.
