COSC 311  Homework 9/14/2016  A programming interview question
Distributed 9/14/2016
Due: 9/19/2016

Write Java code to obtain 3 unique values out of 10 specified values.  That is, 
compute C(10, 3) -- out of 10 values, choose 3 of them, any order, and without replacement.
This is like drawing a hand of 3 cards out of a 10 card deck.

Initialization: Initialize a 1D array size 10 to have unique values [0 .. 9]

Output: Output 3 randomly chosen values from the array. 

Constraints on the output: 
  The values chosen must be unique. 
  Any available choice must have an equal probability of being chosen.

Constraints on the code:
  Do not use any Java objects or classes beyond basic character stream I/O, and
Random.
  Use of Scanner is ok. 
  Do not use Array.
  Do not use Integer.

  The data structure must be int[10].

Note! Each number that will be outputted must have required exactly one call to 
Random's nextInt(int n)

Points taken off for:
  - doesn't work
  - doesn't meet constraints
  - excessive line count
  - improper use of random number generator
      (e.g., using more than one random number generator)
