#include<iostream>
using namespace std;
const int N=1e5+10;
int n,t[N],mx=0,m;
int main(){
	freopen("duel.in","r",stdin);
	freopen("duel.out","w",stdout);
	scanf("%d",&n);
	for(int i=1;i<=n;i++) scanf("%d",&m),t[m]++;
	for(int i=1;i<=N;i++) if(mx<t[i]) mx=t[i];
	printf("%d",mx);
	return 0;
}

T1代码，求指出错误
