Codeforces Round #619 (Div. 2) A. Three Strings

You are given three strings aa , bb and cc of the same length nn . The strings consist of lowercase English letters only. The ii -th letter of aa is aiai , the ii -th letter of bb is bibi , the ii -th letter of cc is cici .

For every ii (1≤i≤n1≤i≤n ) you must swap (i.e. exchange) cici with either aiai or bibi . So in total you'll perform exactly nn swap operations, each of them either ci↔aici↔ai or ci↔bici↔bi (ii iterates over all integers between 11 and nn , inclusive).

For example, if aa is "code", bb is "true", and cc is "help", you can make cc equal to "crue" taking the 11 -st and the 44 -th letters from aa and the others from bb . In this way aa becomes "hodp" and bb becomes "tele".

Is it possible that after these swaps the string aa becomes exactly the same as the string bb ?

Input

The input consists of multiple test cases. The first line contains a single integer tt (1≤t≤1001≤t≤100 )  — the number of test cases. The description of the test cases follows.

The first line of each test case contains a string of lowercase English letters aa .

The second line of each test case contains a string of lowercase English letters bb .

The third line of each test case contains a string of lowercase English letters cc .

It is guaranteed that in each test case these three strings are non-empty and have the same length, which is not exceeding 100100 .

Output

Print tt lines with answers for all test cases. For each test case:

If it is possible to make string aa equal to string bb print "YES" (without quotes), otherwise print "NO" (without quotes).

You can print either lowercase or uppercase letters in the answers.

水题。最终目的是要求a和b一样，这样的话，因为ai或者bi其中之一可以与ci交换，所以如果ai==ci,那么拿bi与ci交换，之后可以得到ai==bi;同理bi==ci，可以拿ai与ci交换，遍历一遍看看能不能满足即可。
