LeetCode ProblemBaseball Game
You are keeping the scores for a baseball game with strange rules. At the beginning of the game, you start with an empty record. You are given a list of strings operations, where operations[i] is the ith operation you must apply to the record and is one of the following: Return the sum of all the scores on the record after applying all the operations. The test cases are generated such that the answer and all intermediate calculations fit in a 32-bit integer and that all operations are valid.

Examples
# Example 1
Input
ops = ["5","2","C","D","+"]
Output
30
# Example 2
Input
ops = ["5","-2","4","C","D","9","+","+"]
Output
27
# Example 3
Input
ops = ["1","C"]

0
Constraints
1 <= operations.length <= 1000
operations[i] is "C", "D", "+", or a string representing an integer in the range [-3 * 104, 3 * 104].
For operation "+", there will always be at least two previous scores on the record.
For operations "C" and "D", there will always be at least one previous score on the record.
