Problem Description
Small W gets two files. There are n integers in each file. Small W wants to know whether these two files are same. So he invites you to write a program to check whether these two files are same. Small W thinks that two files are same when they have the same integer set. For example file A contains (5,3,7,7),and file B contains (7,5,3,3). They have the same integer set (3,5,7), so they are same. Another sample file C contains(2,5,2,5), and file D contains (2,5,2,3). The integer set of C is (2,5),but the integer set of D is (2,3,5),so they are not same. Now you are expected to write a program to compare two files with size of n.
Input
Multi test cases (about 100). Each case contain three lines. The first line contains one integer n represents the size of file. The second line contains n integers $a_1, a_2, a_3, \ldots, a_n$ - represents the content of the first file. The third line contains n integers $b_1, b_2, b_3, \ldots, b_n$ - represents the content of the second file. Process to the end of file. $1 \leq n \leq 100$ $1 \leq a_i , b_i \leq 1000000000$
Output
For each case, output "YES" (without quote) if these two files are same, otherwise output "NO" (without quote).
