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 Python (3.4.3) (judge verdict: Wrong Answer)

import math 
n = int(input())
a = list(map(int,input().split()))
b = list(map(int,input().split()))
ans = 0
ans2 = 0

for i in range(n):
  if a[i] > b[i]:
    ans2 += 1

a = sorted(a)
b = sorted(b)

for i in range(n):
  if a[i] > b[i]:
    print("No")
    ans += 1
    break
    
if ans2 > math.ceil((n-2)/2) and ans == 0:
  print("No")
elif ans == 0:
  print("Yes")
