The hockey event at the Winter Olympics will be happening soon! UselessLeaf will bet with his friends about how the countries will place.
The tournament will be operating in a round-robin fashion. There are
countries competing, numbered from
to
, and they will be split into groups of size
.
matches will then occur in each group, where each country in their group play against each other country in the group once, resulting in a total of
matches. After a match, the winning country gains 3 points, while the losing country gains 0. If it is a tie, both countries gain 1 point.
The tournament ends when all
matches have been played. The countries in each group will then be ranked by their points. If there is a tie, the lower-numbered country should be ranked better (for example, if country
and country
where
got the same number of points, country
should be ranked better than country
).
A time traveller has suddenly appeared and provided UselessLeaf with the results of the
matches. He provides the two countries in the match,
and
, and the result of the match, an uppercase letter
where W
means country
won the match, L
means country
won the match, and T
means the match ended in a tie.
UselessLeaf is participating in a bet where he has to guess the country that places
in each group and needs your help figuring this out!

, 1
is ranked
, while 3
is ranked
.
In group
, there is a tie for first and second in terms of points between 2
and 4
