Description
If Adam’s i:th card beats Eve’s i:th card, then Adam gets one point.
If Eve’s i:th card beats Adam’s i:th card, then Eve gets one point.
A card with higher value always beats a card with a
lower value: a three beats a two, a four beats a three and a two, etc.
An ace beats every card except (possibly) another ace.
If the two i:th cards have the same value, then the
suit determines who wins: hearts beats all other suits, spades beats all
suits except hearts, diamond beats only clubs, and clubs does not beat
any suit.
For example, the ten of spades beats the ten of diamonds but not the Jack of clubs.
This ought to be a game of chance, but lately Eve is
winning most of the time, and the reason is that she has started to use
marked cards. In other words, she knows which cards Adam has on the
table before he turns them face up. Using this information she orders
her own cards so that she gets as many points as possible.
Your task is to, given Adam’s and Eve’s cards, determine how many points Eve will get if she plays optimally.
Input
single positive integer N giving the number of test cases. After that
line follow the test cases.
Each test case starts with a line with a single positive
integer k <= 26 which is the number of cards each player gets. The
next line describes the k cards Adam has placed on the table, left to
right. The next line describes the k cards Eve has (but she has not yet
placed them on the table). A card is described by two characters, the
first one being its value (2, 3, 4, 5, 6, 7, 8 ,9, T, J, Q, K, or A),
and the second one being its suit (C, D, S, or H). Cards are separated
by white spaces. So if Adam’s cards are the ten of clubs, the two of
hearts, and the Jack of diamonds, that could be described by the line

Description
Your task is counting the segments of different colors you can see at last.
Input
The first line of each data set contains exactly one integer n, 1 <= n <= 8000, equal to the number of colored segments.
Each of the following n lines consists of exactly 3 nonnegative integers separated by single spaces:
x1 x2 c
x1 and x2 indicate the left endpoint and right endpoint of the segment, c indicates the color of the segment.
All the numbers are in the range [0, 8000], and they are all integers.
Input may contain several data set, process to the end of file.
Output
Each line of the output should contain a color index that can be seen
from the top, following the count of the segments of this color, they
should be printed according to the color index.
If some color can't be seen, you shouldn't print it.
Print a blank line after every dataset.
