1012 数字分类 测试点8

易错点

测试点8：A2的和为零但不为空的情况

代码

#include <iostream>
#include <cstdio>
#include <iomanip>
using namespace std;
int a[1002];
int main()
{
	int n;
	int cnt1=0;

	int tmp2=1;
	int cnt3=0;

	int cnt42=0;
	int max5=-1;
	cin>>n;
	for(int i=0;i<n;i++){
		cin>>a[i];
		if(a[i]%5==0){
			if(a[i]%2==0){
