@Lisuyang 感谢已关

其次 你的cmp写错了（大概是复制的时候忘把 > 改成 == 了） 应为：

bool cmp(Node a,Node b){
    if(a.n<b.n){
        return 1;
    }
    else if(a.n==b.n&&a.y<b.y){
        return 1;
    }
    else if(a.n==b.n&&a.y==b.y&&a.r<b.r){
        return 1;
    }
    else if(a.n==b.n&&a.y==b.y&&a.r==b.r&&a.num>b.num){
        return 1;
    }
    else{
        return 0;
    }
}
