    while(t--){

        int n,m;
        scanf("%d %d",&n,&m);

        printf("%d ",m);

        int l=1;
        int r=m;
        int ret=0;
        int sr;

            //printf("%d %d AAA\n",l,r);
            if(m/sr-(m%sr==0)<=n-m){
                r=sr-1;
                ret=sr;
            }
            else l=sr+1;
        }

        printf("%d\n",ret);

    }


    return 0;
}

这程序好像有点Bug,我给组数据试试?
