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.Scanner;

public class A446 {

	public static void main(String[] args) {
		Scanner in = new Scanner(System.in);
		int n = in.nextInt();
		
		long volume = 0;
		long capacity = 0;
		
		long best = -1;
		long nextBest = -1;
		
		for(int i = 0; i < n; ++i) {
			volume+= in.nextLong();
		}
		
		for(int i = 0; i < n; ++i) {
			long cap = in.nextLong();
			
			if(cap >= best) {
				nextBest = best;
				best = cap;
			}
			else if(cap > nextBest) {
				nextBest = cap;
			}
			capacity+= cap;
		}
		
		if(best+ nextBest >= volume) System.out.println("YES");
		else System.out.println("NO");
		
	}
