浅浅地刷下题

比较细

*，这水题竟然提交了3次才过😕 。。。 AC代码：

#include<iostream>
using namespace std;
long long n,x,maxn=-100000,minn=100000;
int main(){
	cin>>n;
	for(int i=1;i<=n;i++){
		cin>>x;
		maxn=max(maxn,x);
		minn=min(minn,x);
	}
	cout<<minn<<" "<<maxn;
	return 0;
}

测试点1，测试点6 maxn和minn都一样

	}

}

        }


    }
