Word Game
Description
Three guys play a game: first, each person writes down $n$ distinct words of length $3$. Then, they total up the number of points as follows:
- if a word was written by one person — that person gets 3 points,
- if a word was written by two people — each of the two gets 1 point,
- if a word was written by all — nobody gets any points.
The input consists of multiple test cases. The first line contains an integer $t$ ($1 \leq t \leq 100$) — the number of test cases. The description of the test cases follows.
The first line of each test case contains an integer $n$ ($1 \leq n \leq 1000$) — the number of words written by each person.
The following three lines each contain $n$ distinct strings — the words written by each person. Each string consists of $3$ lowercase English characters.
For each test case, output three space-separated integers — the number of points each of the three guys earned. You should output the answers in the same order as the input; the $i$-th integer should be the number of points earned by the $i$-th guy.

In the first test case:
- The word $\texttt{abc}$ was written by the first and third guys — they each get $1$ point.
- The word $\texttt{def}$ was written by the second guy only — he gets $3$ points.
