Problem Description

After losing all his chips when playing Texas Hold‘em with Fsygd on the way to ZJOI2015, ZCC has just learned a black technology. Now ZCC is able to change all cards as he wants during the game. ZCC wants to get a Straight Flush by changing as few cards as possible.

We call a five-card hand a Straight Flush when all five cards are consecutive and of the same suit. You are given a five-card hand. Please tell ZCC how many cards must be changed so as to get a Straight Flush.
  
Cards are represented by a letter(‘A‘, ‘B‘, ‘C‘, ‘D‘) which denotes the suit and a number(‘1‘, ‘2‘, ?, ‘13‘) which denotes the rank.
  
Note that number ‘1‘ represents ace which is the largest actually. "1 2 3 4 5" and "10 11 12 13 1" are both considered to be consecutive while "11 12 13 1 2" is not.

 

Input

First line contains a single integer T(T=1000) which denotes the number of test cases.
For each test case, there are five short strings which denote the cards in a single line. It‘s guaranteed that all five cards are different.

 

Output

For each test case, output a single line which is the answer.

 

Sample Input

3
A1 A2 A3 A4 A5
A1 A2 A3 A4 C5
A9 A10 C11 C12 C13

 

Sample Output

0
1
2

    char c;
    int tmp,cnt,maxx;
    while(t--)
    {
       memset(status,0,sizeof(status));
       for(int i=0;i<5;i++)
       {
            cin>>c>>tmp;
            status[c-'A'][tmp]=1;
             if(tmp==1)status[c-'A'][14]=1;
       }
       maxx=0;
