답변 형식
배열 총 합과 배열 원소 수를 받아서 연속된 숫자 배열을 찾으면 됩니다.
풀이 조건
1. 배열의 중간에 위치하는 수(연속된 수의 중위값)를 구해주세요.
total과 num으로 쉽게 구할 수 있습니다.
2. 1번의 중위값과 num으로 배열의 시작 값을 구할 수 있습니다.
3. 반복문을 통해 배열을 완성해주세요.
연속된 수이기 때문에 반복문이 쉽습니다.
숫자 올림 또는 내림 함수를 사용하신다면 더 간결한 코드를 작성하실 수 있습니다.
혹시 설명이 부족하시다면 프로그래머스의 테스트케이스를 다음의 방법에 따라 “종이에 손으로” 풀어보시는 것을 권장드립니다.
JAVA 정답

public int[] solution(int num, int total) {
int[] answer = new int[num];
int start;
if(num%2==0){
start = total/num-(num–2)/2;
} else {
start = total/num-(num–1)/2;
}
for(int i=0; i<num; i++){
answer[i] = start;

// int 배열 할당

I was skeptical at first but the bonuses are legit and actually helpful for new players. Give vn10tr88 a try.
Downloading the app was super easy and it runs way better than the mobile browser version. I appreciate how often they update the software to fix bugs and add new features. It really feels like a team that actually listens to their community. npmelbetdownload

I have played at dozens of sites over the years and I can honestly say this one keeps getting better with every visit. The VIP program actually rewards loyal players with perks that make a real difference in my daily sessions. I love how responsive the support chat is whenever I need a quick hand with a question. It is the kind of place that makes you feel like a valued guest instead of just another username. zeetben777
