Java 代码将 1-13 数字分组 - 实现详解

public class NumberGroups { public static void main(String[] args) { int n = Integer.parseInt(args[0]); int[] numbers = new int[13]; for (int i = 0; i < 13; i++) { numbers[i] = i + 1; } int groupSize = 13 / n; int remainder = 13 % n; int start = 0; for (int i = 0; i < n; i++) { int end = start + groupSize; if (remainder > 0) { end++; remainder--; } System.out.print('Group ' + (i + 1) + ': '); for (int j = start; j < end; j++) { System.out.print(numbers[j] + ' '); } System.out.println(); start = end; } }
