$4\mathrm{.}15$ LAB: Varied amount of input data

Statistics are often calculated with varying amounts of input data. Write a program that takes any number of non$-$negative integers as input, and outputs the max and average. A negative integer ends the input and is not included in the statistics. Assume the input contains at least one non$-$negative integer.

Output the average with two digits after the decimal point followed by a newline, which can be achieved as follows:

system. out.printf$(".2\frac{f}{?}$

$,$ average$)$ ;

Ex: When the input is:

$15,20,0,3,-1$

the output is:

$20,9\mathrm{.}50$

$5489824074040\mathrm{.}932947$
