XOJ 1004.Sort Ver.2 From XMU

Description

Give a set of numbers, output them after sort. You may use any algorithm you like to solve it.

Input

Each input file contains only one case.

Each test case begins with an integer N(0<N<=1,000,000), the size of the set.

The Next line contains N numbers, represent the elements of the set. Each number range in [0..2147483647]

Output

Output the set in one line after sort.

Sample Input

4

4 15 8 5

Sample Output

4 5 8 15

Hint

O(n2) algorithm may get Time Limit Exceed. Try O(nlogn) to avoid TLE.
