Answer 1

Recursion in computer science is ,in simple terms, when a function calls itself.The most usual example is the fibonnaci function.In pseudocode:

function fib(int number)
{
if(number==0 || number==1)
return 1;
else return fib(number-1)+fib(number-2); (here we call the function fib from inside the function)
}

That's all about recursion.
