    #### How to play:
                
        - Using +, -, *, / , and () on 4 cards to get 24;
        - Each card represent a number as shown, where J=11, Q=12, K=13, and A=1
        - You will have 3 operations, and you have to express the first and second 
            operation explicitly, e.g. even though you have 6, 6, 6, 6 and you know that
            6 + 6 + 6 + 6 = 24, you need to type your expression clearly as ((6+6)+6)+6 or 
            (6+6)+(6+6) to specify your first two operations.
        - The algorithm encourage thinking of associativity, so, (12/6)*(11+1) and 
            (12/6)*(1+11) would be counted as two different and correct answers.
