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.*;

public class Greed{
	public static void main(String[] args){
		Scanner sc = new Scanner(System.in);
		
		while(sc.hasNext()){
			int n = sc.nextInt();
			int m[] = new int[n];
			long sum = 0L;
    		
    	    for(int i = 0; i < n; i ++){
    			sum = sum + sc.nextInt();
    			}
    			for(int i = 0;i < n;i ++){
    				m[i] = sc.nextInt();
    			}
			
			Arrays.sort(m);
			long t = m[n - 1] + m[n - 2];
			    if(t >= sum){
			        System.out.println("YES");
			    }
			    else{
			            System.out.println("NO");
			        }
		}
	}
