1. The factorial of a nonnegative integer n is written n! (pronounced "n factorial") and is defined as follows: n, = n . (n-1) . (n-2) . . 1 (for values of n greater than 1) and n, = 1 (for n = 0 or n = 1). For example, 5' = 5-4-3 . 2 . 1, which is 120. Use while statements in each of the following: Write a C# Windows Forms Application that reads n from a textbox and display 1! through n! in a list box. Also, estimates the value of the mathematical constant e by using the following formula (with accuracy of 6 decimal places) 1. The factorial of a nonnegative integer n is written n!
