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.
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.

注意顺子仅仅能连到A。
代码：
#include <iostream>
#include <cmath>
#include <cstring>
using namespace std;
bool status[4][15];
int main()
{
int t,n,root;
cin>>t;
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;
for(int i=0;i<4;i++)
{
for(int j=1;j<=10;j++)
{
cnt=0;
if(status[i][j])cnt++;
if(status[i][j+1])cnt++;
if(status[i][j+2])cnt++;
if(status[i][j+3])cnt++;
if(status[i][j+4])cnt++;
if(cnt>maxx)
maxx=cnt;
}
}
cout<<5-maxx<<endl;
}
return 0;
