Here is an algorithm to print out n! (n factorial) from 0! to 19!:

1. Set f = 1 2. Set n = 0 3. Repeat the following 20 times: # use range(1,20) although range(20) will also work but not match #5 a. Output n, "! = ", f b. Add 1 to n c. Multiply f by n Using a for loop, write and run a Python program for this algorithm.

4. Modify the program above using a while loop so it prints out all of the factorial values that are less than 1 billion.
