题目描述
Write a program which reads a sequence of n integers ai(i=1,2,…n), and prints the minimum value, maximum value and sum of the sequence.
输入
In the first line, an integer n is given. In the next line, n integers ai are given in a line.
输出
Print the minimum value, maximum value and sum in a line. Put a single space between the values. [alert title=”注：” icon=”flag” color=”green”]还应该比较max或min与新赋值i的大小[/alert]

#include<bits/stdc++.h>
using namespace std;

max = a; min = a;
while (n > 1) {
scanf(“%d”, &i);
sum = sum + i;
