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 a1,a2,a3,…,an - represents the content of the first file. The third line contains n integers b1,b2,b3,…,bn - represents the content of the second file.
Process to the end of file.
1≤n≤100
1≤ai,bi≤1000000000

 

Output

For each case, output "YES" (without quote) if these two files are same, otherwise output "NO" (without quote).
