16进制

这次涉及十六进制，所以：

struct nod1{
    int g,t;
};
struct nod2{
    char a,b;
};

char number[]={'0','1','2','3','4','5','6','7','8','9','A','B','C','D','E','F'};
nod1 cnt[256];

int turn(char ca,char cb){
    int ia,ib;
    for(int i=0;i<16;i++){
        if(ca==number[i])ia=i;
        if(cb==number[i])ib=i;
    }
    return ia*16+ib;
}

nod2 nrut(int x){
    return {number[x/16],number[x%16]};
}
//turn为16转10，nrut是反过来
