#include<iostream>

using namespace std;

int main(){
    int count , total , j = 0 , k = 0 , decide = 0 ;
    scanf("%d%d" , &count , &total);
    int num , str[total];
    for(int i = 0 ; i < count ; i++){
            int sum = 0 ;
            int top = 0 ;  
            for(j = 0 ; j < total ; j++)/**輸入第一行字串*/
                    cin >> str[j];
            for(int k = 0 ; k < total ; k++){
                    cin >> num; /**讀取*/
                    for(j = top ; j < total ; j++)/**搜尋*/
                          if(num < str[j]){/**如果字串大於搜尋，因為題目字串是循序*/
                                    top = j ;
                                    break;
                          }
                          else if(num == str[j]){/**如果相等*/
                                    top = j ;
                                    sum++ ;
                                    break;
                          }
            }
            cout << sum << endl;
    }
    system("PAUSE");
    return 0;
}

這是我的程式碼，

請高手給個指教謝謝!!
