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 CPP):

Solution:
#include <bits/stdc++.h>
using namespace std;
struct curve {
  int ost, ob;
};
bool operator<(const curve &a, const curve &b) { return a.ob > b.ob; }
int main() {
  int n;
  cin >> n;
  curve *a = new curve[n];
  for (int i = 0; i < n; i++) cin >> a[i].ost;
  for (int i = 0; i < n; i++) cin >> a[i].ob;
  sort(a, a + n);
  int s = a[0].ob + a[1].ob;
  for (int i = 0; i < n; i++) {
    s -= a[i].ost;
    if (s < 0) {
      cout << "no";
      return 0;
    }
  }
  cout << "yes";
  return 0;
}
