通过进栈出栈实现循环

#include<iostream>
#include<queue>
using namespace std;
queue<int> q;
int main(){
    int n,m;
    cin>>n>>m;
    for(int i=1;i<=n;i++)
        q.push(i);
    int num=1;
    while(!q.empty()){
        if(num==m){
            cout<<q.front()<<" ";
            q.pop();
            num=1;
        }
        else{
            q.push(q.front());
            q.pop();
            num++;
        }
    }   
    return 0;
}
