You are given a list consisting of $n$ integers. Your task is to remove elements from the list at given positions, and report the removed elements.
The first input line has an integer $n$ : the initial size of the list. During the process, the elements are numbered $1,2,\dots,k$ where $k$ is the current size of the list.
The second line has $n$ integers $x_1,x_2,\dots,x_n$ : the contents of the list.
The last line has $n$ integers $p_1,p_2,\dots,p_n$ : the positions of the elements to be removed.
Print the elements in the order they are removed.

The contents of the list are $[2,6,1,4,2]$ , $[2,6,4,2]$ , $[6,4,2]$ , $[6,4]$ , $[4]$ and $[]$ .
