In mathematics, the notation n! represents the factorial of the nonnegative integer n. The factorial of n is the product of all the non-negative integers from 1 to n. For example: 7! = 1 2 3 4 5 6 7 = 5,040 and 4! = 1 2 3 4 = 24 Write a program that lets the user enter a nonnegative integer then uses a loop to calculate and display the factorial of that number. Your output should be formatted like the following: Enter a non-negative integer: 10 The factorial of 10 is: 10! = 1 2 3 4 5 6 7 8 9 10 = 3,628,800 Another example: Enter a non-negative integer: 5 The factorial of 5 is: 5! = 1 2 3 4 5 = 120 Hint: This isnt as easy as it looks. You will need to concatenate a string inside of your loop and have conditional decisions to build the 1 2 3 output (every loop does one thing except for the last). Note that this does not use a lowercase X but the multiplication symbol which is: \u02df just like we did with the degree symbol in Chapter 2
