Given 3 ints return their sum.
However, if one of the values is 13 then it does not count towards the sum and values to its right do not count.
So for example, if the second int is 13, then both it and the third int do not count.
For this problem we're expecting only a method.
Don't define a class, include modifiers like static or public, add import statements, or add code outside the method declaration.
