  int[] numbers = new int[m]; for (int i = 0; i < m; i++) { numbers[i] = scanner.nextInt(); } boolean first = true; for (int i = 0; i < m; i += n) { if (!first) { System.out.print(" "); } if (numbers[i] % p == 0) { System.out.print(0); } else { System.out.print(numbers[i] * p); } first = false; // 之後的數字都要加空格 } System.out.println(); // 換行 scanner.close();
