基础练习 数列特征

本题不多说，注意一个细节，就是maxn和minn在初始化的时候应该初始化为负无穷和正无穷

#include<cstdio>
int main()
{
	int n;
	//freopen("9.txt","r",stdin);
	scanf("%d",&n); 
	int a[n];
	int maxn=-100000000,minn=0xfffffff;
	long long sum=0;
	for(int i=0;i<n;i++)
	{
		scanf("%d",&a[i]);
		sum+=a[i];
		if(a[i]>maxn)
			maxn=a[i];
		if(a[i]<minn)
			minn=a[i];
	}
	printf("%d\n%d\n%I64d\n",maxn,minn,sum);
	
	return 0;
}
