Given a string of numbers and operators, return all possible results from computing all the different possible ways to group numbers and operators. The valid operators are +
, -
and *
.
Example 1:
Input: "2-1-1" Output: [0, 2] Explanation: ((2-1)-1) = 0 (2-(1-1)) = 2
Example 2:
Input: "2*3-4*5" Output: [-34, -14, -10, -10, 10] Explanation: (2*(3-(4*5))) = -34 ((2*3)-(4*5)) = -14 ((2*(3-4))*5) = -10 (2*((3-4)*5)) = -10 (((2*3)-4)*5) = 10
