Problem: Jafar has n cans of cola. Each can is described by two integers: remaining volume of cola ai and can's capacity bi (ai ≤  bi).

Jafar has decided to pour all remaining cola into just 2 cans, determine if he can do this or not!

Input

The first line of the input contains one integer n (2 ≤ n ≤ 100 000) — number of cola cans.

The second line contains n space-separated integers a1, a2, ..., an (0 ≤ ai ≤ 109) — volume of remaining cola in cans.

The third line contains n space-separated integers that b1, b2, ..., bn (ai ≤ bi ≤ 109) — capacities of the cans.

Output

Print "YES" (without quotes) if it is possible to pour all remaining cola in 2 cans. Otherwise print "NO" (without quotes).

You can print each letter in any case (upper or lower).

Examples

Input

2
3 5
3 6


Output

YES


Input

3
6 8 9
6 10 12


Output

NO


Input

5
0 0 5 0 0
1 1 8 10 5


Output

YES


Input

4
4 1 0 3
5 2 2 3


Output

YES

Note

In the first sample, there are already 2 cans, so the answer is "YES".

Solution (in JAVA):

Solution:

import java.util.Arrays;
import java.util.Collections;
import java.util.Scanner;

public class problem95 {

	public static void main(String[] args) {
		// TODO Auto-generated method stub
		Scanner sc = new Scanner(System.in);
		int n = sc.nextInt();
		long rem[] = new long[n];
		Long act[] = new Long[n];
		long remvol=0;
		for(int i=0;i<n;i++)
		{
			rem[i] = sc.nextLong();
			remvol = remvol+rem[i];
		}
		for(int i=0;i<n;i++)
		{
			act[i]  = sc.nextLong();
		}
		Arrays.parallelSort(act,Collections.reverseOrder());
		long actvol = 0;
		actvol = act[0]+act[1];
		if(actvol>=remvol)
			System.out.println("yes");
		else
			System.out.println("no");
