蓝桥杯：六角填数问题

标题：六角填数
如图【1.png】所示六角形中，填入1~12的数字。
使得每条直线上的数字之和都相同。
图中，已经替你填好了3个数字，请你计算星号位置所代表的数字是多少？

答案：9 10 6 5 4 11 12 2 7

代码：

public class LiuJiao {
    public static void main(String[] args) {
        for (int c21 = 2; c21 < 12; c21++) {//B
            if(c21==3||c21==8) continue;
            for (int c22 = 2; c22 < 12; c22++) {//C
                if (c22==3||c22==8||c21==c22) continue;
                for (int c31 = 2; c31 < 12; c31++) {//D
                    if (c31==3||c31==8||c21==c31||c22==c31) continue;
