Recursion is a process in which a function invokes itself, and the corresponding function is called a recursive function.
Recursion is one of those topics in programming that often confuses students, and in this video, I'm explaining how recursion works and also comparing different solutions to the same problem (using loops and using recursion)

I have questin for you , why varible ' m ' doesn't equal to parameter 'm' through recursion ?

If first number is larger than second number, no need to swap values, just call the function with reversed arguments in an else block, like, if (n

Thanks a lot, Saldina for these amazing videos, they are very helpful. Code for finding the factorial with a recursive function, #include using namespace std; int recursive_factorial(int num){ if(num == 1) return num; return num * recursive_factorial(num - 1); } int main() { cout > num; cout
