You have 4 cards each containing a number from 1 to 9.  You need to judge whether they could operated through *, /, +, -, (, ) to get the value of 24.


Example 1:

Input: [4, 1, 8, 7]
Output: True
Explanation: (8-4) * (7-1) = 24



Example 2:

Input: [1, 2, 1, 2]
Output: False



Note:

The division operator / represents real division, not integer division.  For example, 4 / (1 - 2/3) = 12.
Every operation done is between two numbers.  In particular, we cannot use - as a unary operator.  For example, with [1, 1, 1, 1] as input, the expression -1 - 1 - 1 - 1 is not allowed.
You cannot concatenate numbers together.  For example, if the input is [1, 2, 1, 2], we cannot write this as 12 + 12.
