The factorial of a number, N, is defined as follows:

N! = 1 * 2 * 3 * 4 *.....* N

For example, 4! = 1 * 2 * 3 * 4 and 7! = 1 * 2 *3 * 4 * 5 * 6 * 7

Create a web page that allows the user to enter a positive integer and the page will display the factorial of that number. (Just the answer) Hint: Use a counter variable and factorial variable with an initial value of 1. Then use a loop to multiply factorial by successive integers up to the value entered by the user.
