You are given a sorted sequence of n integers S = s₁, s₂ ... s_n and a sorted sequence of m integers Q = q₁, q₂ ... q_m.

Please print in ascending order all such s_i that does not belong to Q.

Input data specification

In the first line you are given one integer 2 <= n <= 100, and in the following line n integers:
-100 <= s_i <= 100, s_i <= s_i+1.

In the third line you are given one integer 2 <= m <= 100, and in the following line m integers:
-100 <= q_i <= 100, q_i <= q_i+1.

Output data specification

The sequence of requested integers separated by spaces.

Example

Input:
5
-2 -1 0 1 4
6
-3 -2 -1 1 2 3

Output:
0 4
