Merge two sorted arrays

Given two sorted arrays and of lengths n and m, you are asked to obtain a new array by combining those two that would be sorted as well.

Input

The first line of the input contains two integers n and m (1 ≤ n, m ≤ ).

The second line contains n space-separated sorted integers ( ≤ ≤ ).

The last line contains m space-separated sorted integers ( ≤ ≤ ).

Output

The program should print n+m space-separated integers in increasing order representing the combination of a and b.
