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.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.util.Arrays;


public class Main {

    public static void main(String[] args) throws IOException {
        BufferedReader in = new BufferedReader(new InputStreamReader(System.in));
        String[] arr;
        int[] resultArr;
        int a,b,k,n,paper,rounds,maxNum,p,countStrings=0;
        arr = in.readLine().split(" ");
        n = Integer.valueOf(arr[0]);

        int maxV=0,subMax = 0;
        Long sum = 0L;
        arr = in.readLine().split(" ");
        for (int i = 0; i < n; i++) {
            a = Integer.valueOf(arr[i]);
            sum+=a;
        }
        arr = in.readLine().split(" ");
        for (int i = 0; i < n; i++) {
            b = Integer.valueOf(arr[i]);
            if (b>=subMax){
                if(b>=maxV){
                    subMax=maxV;
                    maxV=b;
                }else{
                    subMax=maxV;
                }
            }
        }
        if(sum<=maxV+subMax){
            System.out.println("YES");
        }else {
            System.out.println("NO");
        }
    }
