样例能跑通

Code:

#include<bits/stdc++.h>
using namespace std;
int main()
{
	int n,m;
	cin>>n>>m;
	int a[n+1];
	int b[m+1];
	for(int i=1;i<=n;i++){
		cin>>a[i];
	}
	for(int i=1;i<=m;i++)
	cin>>b[i];
	int c[n+1]={0};
	int ans1=1;
	for(int i=1;i<=m;i++){
		if(b[i]<=5){
		c[ans1]=b[i];
		ans1++;
		cout<<b[i]<<endl;
		}
	}
	int ans=0;
	for(int i=1;i<ans1;i++){
		if(a[c[i]]<200){
		ans++;
		cout<<a[c[i]]<<" ";
		}
	}
	cout<<ans;
	return 0;
}
