Describe the bug
두 정수의 계산 범위가 int 타입의 표현 범위를 초과하는 경우 계산 결과가 틀리게 출력됩니다.

To Reproduce

  1. 프로그램을 실행합니다.
  2. 입력으로 2000000000 2000000000 입력합니다.
  3. 실행 결과는 2000000000 + 2000000000 = -294967296 으로 틀린 계산 결과가 발생합니다.
$ build/calc
$ 2000000000 2000000000
$ 2000000000 + 2000000000 = -294967296

Expected behavior

기대하는 출력 결과는 2000000000 + 2000000000 = 4000000000 입니다.
