ACM比赛（11462 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 le. Each case starts with an integer

n(0<=n<=200000)

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.

Sample Input

5

3 4 2 1 5

5

2 3 2 3 1

0

Sample Output

1 2 3 4 5

1 2 2 3 3

程序分析：此题的考点是一个数组数据的排序，值得注意的是此题如果自己写一排序函数（选择法、冒泡法、插入法)会比较耗时导致程序通不过，所以我们可以考虑使用sort函数。还有就是可能会有很多会把数组a开在主函数，非常建议大家不要这样，这样也会很耗时。

程序代码：

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

}
return 0;
}
