Problem Description
　　We all use cell phone today. And we must be familiar with the intelligent English input method on the cell phone. To be specific, the number buttons may correspond to some English letters respectively, as shown below:
　　2 : a, b, c    3 : d, e, f    4 : g, h, i    5 : j, k, l    6 : m, n, o    
　　7 : p, q, r, s  8 : t, u, v    9 : w, x, y, z
　　When we want to input the word “wing”, we press the button 9, 4, 6, 4, then the input method will choose from an embedded dictionary, all words matching the input number sequence, such as “wing”, “whoi”, “zhog”. Here comes our question, given a dictionary, how many words in it match some input number sequences?
 

Input
　　First is an integer T, indicating the number of test cases. Then T block follows, each of which is formatted like this:
　　Two integer N (1 <= N <= 5000), M (1 <= M <= 5000), indicating the number of input number sequences and the number of words in the dictionary, respectively. Then comes N lines, each line contains a number sequence, consisting of no more than 6 digits. Then comes M lines, each line contains a letter string, consisting of no more than 6 lower letters. It is guaranteed that there are neither duplicated number sequences nor duplicated words.
 

Output
　　For each input block, output N integers, indicating how many words in the dictionary match the corresponding number sequence, each integer per line.

 題目意思就不多說了，將下面的字串hash對映到上面的數字上即可。





AC程式碼：




#include<iostream>
#include<cstring>
using namespace std;
int hash1[1000005];
int a[5005];
char b[5005][8];

int cal(char *s)
{
    int tmp=0;
    int len=strlen(s),i;
    for(i=0;i<len;i++)
    {
        if(s[i]>='a'&&s[i]<='c')       tmp=tmp*10+2;
        else if(s[i]>='d'&&s[i]<='f') tmp=tmp*10+3;
        else if(s[i]>='g'&&s[i]<='i') tmp=tmp*10+4;
        else if(s[i]>='j'&&s[i]<='l') tmp=tmp*10+5;
        else if(s[i]>='m'&&s[i]<='o') tmp=tmp*10+6;
        else if(s[i]>='p'&&s[i]<='s') tmp=tmp*10+7;
        else if(s[i]>='t'&&s[i]<='v') tmp=tmp*10+8;
        else if(s[i]>='w'&&s[i]<='z') tmp=tmp*10+9;
    }
    return tmp;
}

int main()
{
    int tes,i;
    cin>>tes;
    while(tes--)
    {
        int n,m;
        cin>>n>>m;
        for(i=0;i<n;i++)
            cin>>a[i];   //存放數字
        for(i=0;i<m;i++)
            cin>>b[i];
        memset(hash1,0,sizeof(hash1));
        for(i=0;i<m;i++)
            hash1[cal(b[i])]++;
        for(i=0;i<n;i++)
            cout<<hash1[a[i]]<<endl;
    }
    return 0;
}
