The output format says:
Print Q
And then Print Q lines of the form
NumSheme Count

But the sample output is written
2
1 2
3
Why there isn't any '1' after the 3.

And what does the sentence:
'Numbers in each line of the output must be sorted in
increasing order' mean? How can you sort NumSheme and Count
when it is said that they should be ano after another in a
strict way?

The output is wrong - but not in the way you describe.

All three die are different - note 1 dot opposite 2 dots, 3
dots and 4 dots for the three die respectively.

The output should read:
3
1
2
3

This is the number of different die types followed by the
die in each type in increasing order.

No, sample output is correct. Sample input is wrong.
Fixed.

'Next Q lines should contain the numbers of dice with the
same scheme. '

It is the numbers, not the count.
