Consider the following method.

public static void whileMystery(int n) { 
    int x = 0; 
    int y = 1; 
    while (n > x && n > y) { 
        n--; 
        x = x + 2; 
        y = y + x; 
    } 
    System.out.println(x);
}

For each call below, indicate what output is produced.

whileMystery(5);
whileMystery(10);
whileMystery(4);
