This flowchart answers the question "How do you draw a flowchart to calculate N factorial?" N factorial is represented as N! where the exclamation point means factorial. For example,
1! = 1
2! = 1*2 = 2
3! = 1*2*3 = 6
4! = 1*2*3*4 = 24
N! = 1*2*3...*N
N is an integer and is the input to the flowchart. This flowchart has a loop
that starts with M = 1 and increments M until M equals
the inputted value N. This program calculates N! by doing each multiplication.
Since a computer can rapidly do calculations, it can implement a brute force
solution rather than having to rely on a more elegant one.
The next question might be "Can you find a function that computes N! from
N without doing each multiplication?"
