Write a program which repeatedly reads numbers until the user enters "done". Once "done" is entered, print out the total, count, and average of the numbers.

Enter a number: $4$

Enter a number: $5$

Enter a number: $7$

Enter a number done

Exercise $2$: Write another program that prompts for a list of numbers as above and at the end prints out both the maximum and minimum of the numbers instead of the average.

Enter a number: $4$

Enter a number: $5$

Enter a number $7$

Enter a number done

Maximum $=7\mathrm{.}0$

Minimum $4\mathrm{.}0$
