2015 HUAS Provincial Select Contest #1 B

题目：

Age Sort You are given the ages (in years) of all people of a country with at least 1 year of age. You know that no individual in that country lives for 100 or more years. Now, you are given a very simple task of sorting all the ages in ascending order.

Input

There are multiple test cases in the input file. Each case starts with an integer n (0 < n ≤ 2000000), the total number of people. In the next line, there are n integers indicating the ages. Input is terminated with a case where n = 0. This case should not be processed.

Output

For each case, print a line with n space separated integers. These integers are the ages of that country sorted in ascending order.

Warning: Input Data is pretty big (∼ 25 MB) so use faster IO.

题目大意：输入N个数 将它们按从小到大排序，遇到输入0程序结束

解题思路：讲输入的N个数存储到数组中，利用头文件algorithm中的sort（）函数排列，再输出；

代码：

 

#include<iostream>
#include<cstdio>
#include<algorithm>
using namespace std;
int main()
{
    int* a;
    int n;
    while(cin>>n)
    {
        if(n>0&&n<=2000000)
        {
            a=new int[n];
            for(int i=0;i<n;i++)
                scanf("%d",&a[i]);
            sort(a,a+n);
            for(int j=0;j<n;j++)
            {
                if(j!=(n-1))
                printf("%d ",a[j]);
                else  printf("%d",a[j]);
            }
            printf("\n");
        }
        else break;
    }
    return 0;
}
