There is a problem in my code which i can't see where it is. Please read the description of this project(http://people.cs.umass.edu/~liberato/courses/2017-spring-compsci190d/assignments/programming-assignment-11-war/)go to this link. It is just a simple war card game.

/**

*

* A Java class to simulate the card game War. See assignment writeup for details.

public class War {

/**

* Determines the winner of a game of War, returning 1 if player A wins, -1 if player B wins, 0 if a draw.

*

* The rules of the game are defined in the assignment writeup.

*

* @param deck

* @return 1 if player A wins, -1 if player B wins, 0 if a draw
