B'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: The input consists of multiple test cases. The first line contains an integer t ( 1 <= q t <= q 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 <= q n <= q 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: '...
