CF1722C.Word Game

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.

In the end, how many points does each player have?

三人进行一场比赛：首先，每人写下 $n$ 个互不相同的、长度为 $3$ 的单词。然后，按如下规则统计总分：

• 若某个单词仅由一人写出，则该人得 $3$ 分；
• 若某个单词由两人写出，则这两人各得 $1$ 分；
• 若某个单词由三人全部写出，则无人得分。

最终，每位玩家各得多少分？

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.

输入包含多个测试用例。第一行包含一个整数 $t$（$1 \leq t \leq 100$），表示测试用例的数量。随后是各测试用例的描述。

每个测试用例的第一行包含一个整数 $n$（$1 \leq n \leq 1000$），表示每人所写的单词数量。

接下来的三行，每行包含 $n$ 个互不相同的字符串，分别表示三人所写的单词。每个字符串均由 $3$ 个小写英文字母组成。

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.

对于每个测试用例，输出三个以空格分隔的整数——即三位选手各自获得的分数。你需要按照输入的相同顺序输出答案；第 $i$ 个整数应为第 $i$ 位选手获得的分数。

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.

在第一个测试用例中：

• 单词 $\texttt{abc}$ 由第一位和第三位参与者写出——他们每人获得 $1$ 分。
• 单词 $\texttt{def}$ 仅由第二位参与者写出——他获得 $3$ 分。
