the factorial of an integer is the product of that integer multiplied by all the positive non-zero integers less than that integer. so, 5! (! is the mathematical symbol for factorial) is . 4! is , so 5! could be written as 5 * 4!. so a recursive definition of factorial is n! is n*(n-1)!, as long as n >1. 1! is 1. what is the recursive call for this function (fact)?
