COSC 311 Homework 1/5/2017  Compute prefix sums
Distributed: 1/5/2017
Due: 1/10/2017

Write Java code to compute prefix sums of an array of ints. The prefix sums
are put in a different array than the input. Do not smash the input data.

Initialization: Initialize a 1D array with int values. The zeroth array data element
must be 0.

Output: The prefix sums.

Each value in the prefix sum array is the sum of all the data array values from 
index 0 up to and including the current index value.

Example:
data     0   5   1   -3   2   0   4
prefSum  0   5   6   3    5   5   9

Turn in:
  Hardcopy of your code.
  In your code, include a header:
      [your name]
