hdoj-1276-士兵队列训练问题(队列模拟)

题意:

新兵蛋子按照两种报数规则报数:

1.1212报数,2出队

2.123123报数,3出队

没报完一轮,检查人数,不大于3,over

略坑,必须每报完一轮检查人数,最初,按照12两种顺序报完检查人数,WA了

        while (Q.front() != 1) {//调整顺序
            Q.push(Q.front()), Q.pop();
        }
        cout<<Q.front();//注意格式
        Q.pop();
        while (!Q.empty()) {
            cout<<" "<<Q.front();
            Q.pop();
        }
        cout<<endl;
    }
    return 0;
