NYOJ 86 找球号(一) (map)

题目链接:http://acm.nyist.edu.cn/JudgeOnline/problem.php?pid=86

        直接用map实现...


AC代码:

#include <iostream>
#include <cstdio>
#include <cstring>
#include <map>
using namespace std;
int n,m;
map<int,int> ma;
int pre[1000005];
 
int main()
{
  scanf("%d%d",&n,&m);
  for(int i=0;i<n;i++){
    scanf("%d",&pre[i]);
    ma[pre[i]] = 1;
  }
  while(m--){
    int x;
    scanf("%d",&x);
    if(ma[x] == 1){
      printf("YES\n");
    }
    else{
      printf("NO\n");
    }
  }
  return 0;
}
