TASK $4($OF $4)$

Write a Python script which computes the factorial of a number using a loop $($do not use math.factorial$).$ Your program should prompt the user for a non$-$negative integer, $n.$ Recall that the factorial of a number, $n,$ is defined as:

$nn**(n-1)**(n-2)**dots.**2**1$

Recall also that $01,$ and that we cannot calculate the factorial of a negative number or a float $($decimal number$).$

Ensure your number is not a decimal by using the int$()$ function in your input line.

Use a loop to ensure that your input is not negative. If the user enters a negative value, your program should repeatedly ask the user for a non$-$negative integer until the user enters a non$-$negative integer.

Your program should output $($using print$0)$ a mathematical expression showing the numeric input from the user and its factorial. For example, if the user enters $5,$ the output should look
