using namespace std; int main(){ int row,count1=0,max1=0; cin>>row; vector> myvector(row); for(int i=0;i>col; myvector[i]=vector (col); for(int j=0;j>myvector[i][j]; }

}
for(int i=0;i<myvector.size();i++){
    for(int j=0;j<myvector[i].size()-1;j++){
        if(myvector[i][j]>myvector[i][j+1] || myvector[i][j+1]<max1 ){
            max1=myvector[i][j];
            count1++;
        }
    }
    if(count1>1)
    cout<<"NO\n";
else
    cout<<"YES\n";
}
