If the value of 'N' is 2, 'A' is "ab" , 'B' is "aa" and 'C' is "bb".
Then the answer for this input is
min = 2
max = 2
Because current difference is 1 + 1 = 2
After one rotation difference will be 1 + 1 = 2
Hence, the minimum and the maximum answer is 2.
```

```
The first line contains a single integer 'T' denoting the number of test cases to be run. Then the test cases follow.
First line: Single integer 'N' (the length of the three strings)
Following three lines: Strings 'A, 'B', and 'C', respectively.
```

```
For each test case, Print two space-separated integers denoting the maximum and minimum difference of the three strings for all possible rotations of string a.
Output for each test case will be printed in a separate line.
```

```
You are not required to print anything; it has already been taken care of. Just implement the function.
```

```
1 <= T <= 50
1 <= N <= 10^4
Time Limit: 1 sec.
