COSC 311  Homework 11/15    

Distributed: 11/15/2017     Due: 11/29/2017

Write a Java program that has two user-supplied (at run-time) inputs:

d -- this is the number of 6-sided (fair) die
n -- this is a threshold value

One roll of the dice produces a value which is the sum of each die.
  
  
For d and n, how many combinations (rolls of d dice) produce sum >= n?

Example: d = 2, n = 10.
 There are 4 rolls that equal or exceed the threshold:
 5, 5
 6, 5
 5, 6
 6, 6
 
Output:
  Echo d and n values
  Output the number of combinations that are >= n
    (do not output the actual combinations)
  Output the time required to compute answer for given d, n
  
Constraints:
  (1) URL of source files must appear in file header
  (2) No more than 5 lines of reasonable comments
  
Turn in:
  (1) Source code
  (2) Screen shot on runs for:
    d   n
  ---------
    2   10
    10  50
    20  100
    50  250
    100 500
    
  (3) Graph of time (y axis) versus d (x-axis).
  
Points taken off for:
(1) Doesn't work
(2) Failure to meet constraints
(3) Code does not match output
(4) Ugly or difficult to understand code
(5) No graph.
