Write a program to read a list of nonnegative integers and to display the largest integer, the smallest integer, and the average of all the integers. The user indicates the end of the input by entering a negative sentinel value that is not used in finding the largest, smallest, and average values. The average should be a value of type double so that it is computed with a fractional part.

Input Notes: The input is simply a sequence of positive integers, separated by white space and terminated by -1.

SAMPLE RUN #1: java LargeSmallAverage

Interactive Session

This program allows you to enter a list of positive integers (terminated by a -1) then displays the largest value, smallest value, and average of the list of numbers, not including the final (negative) value that ends the list. Enter a positive integer, or -1 to quit:-1 You did not enter any positive integers.
