an algorithm to compute the factorial of an integer n would look like this:
 
1.  initialize a variable to 1. 
2.  loop through all integers from 1 up to n. 
3.  for every integer i, multiply the current value of the variable by i.
4.  when the loop ends, the value of the variable will be the factorial of n.
