Write a function that returns the team +/- for the home team given an array of scores.

“team +/-” means the total difference between the points scored by the home team and the points given up. It could be a negative number.

Scores will be in a 2-D array in the format:

int[][] games = {
    {84, 92},
    {95, 93},
    {86, 88},
    {86, 83},
    {112, 103},
    {105, 95}
};

Each “game” will have two numbers: the home score and the away score.

You should write a function called teamPlusMinus that takes a parameter games and computes the total +/- of these games for the home team.
