Problem Statement

Given are two integer sequences of N elements each: A_1,...,A_N and B_1,...,B_N.
Determine if it is possible to do the following operation at most N-2 times (possibly zero) so that, for every integer i from 1 to N, A_i \leq B_i holds:

Choose two distinct integers x and y between 1 and N (inclusive), and swap the values of A_x and A_y.

Constraints

2 \leq N \leq 10^5

1 \leq A_i,B_i \leq 10^9

Input

Input is given from Standard Input in the following format:

N
A_1 A_2 ... A_N
B_1 B_2 ... B_N

Output

If the objective is achievable, print Yes; if it is not, print No.

Sample Input 1

3
1 3 2
1 2 3

Sample Output 1

Yes

We should swap the values of A_2 and A_3.

Sample Input 2

3
1 2 3
2 2 2

Sample Output 2

No

Sample Input 3

6
3 1 2 6 3 4
2 2 8 3 4 3

Sample Output 3

Yes

Solution in PyPy3 (2.4.0) (judge verdict: Wrong Answer)

N = int(input())
A = list(map(int, input().split()))
B = list(map(int, input().split()))

def count_loop(start, idx_map):
    count = 0
    idx = start
    while idx != 0:
        idx = idx_map[idx]
        count += 1
    return count

idx_map = sorted(range(N), key=lambda i: A[i])
A.sort()
B.sort()

check_1 = all(A[i] <= B[i] for i in range(N))
check_2 = any(A[i + 1] < B[i] for i in range(N - 1))
check_3 = count_loop(0, idx_map) < N
print("Yes" if check_1 and (check_2 or check_3) else "No")
