Interesting to now, why when I write like this:
     int map[50001][4];
    int N;
    cin >> N;
    for (int i=0; i<N; i++)
    {
        scanf("%d %d %d %d", &map[i][0], &map[i][1], &map[i][2], &map[i][3]); ...
I got wa2
 and when I write like this:

    for (int i=0; i<N; i++)
    {
        cin >> map[i][0] >> map[i][1] >> map[i][2] >> map[i][3];..
 I succesfully pass second test
?

don't mix cin and scanf!
