정수 num1과 num2가 매개변수로 주어질 때, num1을 num2로 나눈 값에 1,000을 곱한 후 정수 부분을 return 하도록 soltuion 함수를 완성해주세요. class Solution { public int solution(int num1, int num2) { double answer = (double) num1 / num2 * 1000; return (int)answer; } }

정수 num1과 num2가 주어질 때, num1과 num2의 합을 return하도록 soltuion 함수를 완성해주세요. class Solution { public int solution(int num1, int num2) { int answer = -1; answer = num1 + num2; return answer; } }
