You are given an array A of size N. you need to insert the elements of A into a multiset and display the results. Also, you need to erase a given element x from the multiset and print "erased x" if successfully erased, else print "not found".

Input Format:
The first line of input contains T denoting the number of testcases. T testcases follow. Each testcase contains three lines of input. The first line contains N denoting the size of the array A. The second line contains N elements of the array. The third line contains element x that need to be erased from the set.

Output Format:
For each testcase, in a new line, print the required output.

Your Task:
Since this is a function problem, you don't need to take any input. Just complete the provided functions.

1 <= T <= 100
1 <= N <= 1000
1 <= Ai <= 106
