자바로 한번 풀어볼 겸 쉬운 문제를 풀어보았다.

import java.io.BufferedReader;

        }

        st = new StringTokenizer(br.readLine());

        int C = Integer.parseInt(st.nextToken());
         long  sum = n;

                continue;
            int num = arr[i] / C;
            if (arr[i] % C != 0)
                num++;
            sum += num;

        System.out.println(sum);
    }
