**Problem Description**

For example, if there are 5 rounds and player A plays (in this order) 5, 3, 1, 3, 5 and player B plays 3, 3, 3, 3, 4, then the scoring for each round would be: A gets 5 points, no points, B gets 3 points, no points, B gets 9 points. The totals would be A: 5, B: 12.

In this problem you will be given card plays for both players and must determine the final scores.

**Input**

There will be multiple input instances. Each instance will be one game. The first line of input for a game will be an integer n <= 20. (A value of n = 0 terminates input.) The next two lines will each contain n integers between 1 and 5 inclusive indicating the cards played on each of n rounds. The first line are player A's card plays and the second line are player B's card plays.

**Output**

Each input instance should generate one line of output of the form:

A has a points. B has b points.

where the value of a and b are for you to determine. A blank line should separate output lines.

**Sample Input**

5 5 3 1 3 5 3 3 3 3 4 4 2 3 1 1 1 5 5 5 0

**Sample Output**

A has 5 points. B has 12 points. A has 0 points. B has 21 points.
