Language/Type: Java file processing Scanner
Author: Marty Stepp (on 2020/04/08)

Write a static method purpleGold that accepts as a parameter a Scanner that reads its input from a file containing a series of names followed by integers. The names alternate between purple team member names and gold team member names. Your method should compute the absolute difference between the sum of the purple teams' integers and the sum of the gold teams' integers. The input could end with either a purple or gold team member; you may not assume that it contains an even number of names. If the input file tas.txt contains the following text,

Chloe 3 Eyad 7 Noa 14 James 13 Nile 4 Kelvin 12 Justin 6 Mitchell 0

Then your method could be called in the following way:

Scanner input = new Scanner(new File("tas.txt"));

And produces this console output, since the purple team's sum is 3+14+4+6 = 27 and the gold team's sum is 7+13+12+0 = 32:

4 purple, 4 gold
Difference between purple team and gold team sums: 5
