Using a Stack to Manage Scores

  1. Initialize an empty stack to store the scores.
  2. Iterate through each operation in the operations list.
    • If the operation is an integer (as a string), parse it to an integer and push it onto the stack.
    • If the operation is a '+', calculate the sum of the last two scores in the stack and push the result onto the stack.
    • If the operation is a 'D', double the last score in the stack and push the result onto the stack.
    • If the operation is a 'C', pop the last score from the stack to remove it.
  3. After processing all operations, sum up all the scores in the stack.
  4. Return the total sum as the final result.
