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', $\cdots$, '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.
