Given two lists V1 and V2 of sizes n and m respectively. Return the list of elements common to both the lists and return the list in sorted order. Duplicates may be there in the output list.

Example:

Input:
5
3 4 2 2 4
4
3 2 2 7

Output:
2 2 3

Explanation:
The first list is {3 4 2 2 4}, and the second list is {3 2 2 7}. 
The common elements in sorted order are {2 2 3}

User Task:
This is a function problem. You need to complete the function common_element that takes both the lists as parameters and returns a list of common elements.

Constraints:
1 <= n, m <= 10⁵
1 <= V_i <= 10⁵
