Apple Exchange

Limits: 2 sec., 256 MiB

There are \(n\) people numbered from 1 to \(n\). They exchanged apples according to the following rules:

• each person could give each other person at most one apple;

• in addition, each person could keep at most one apple; such an apple counts as both given and received by that person.

It is known that person number \(i\) gave away exactly \(a_i\) apples and received exactly \(b_i\) apples. Determine whether such an exchange could have happened.

Input

The first line contains one integer \(n\) – the number of people.

The second line contains \(n\) integers \(a_1, a_2, \ldots, a_n\) – how many apples each person gave away.

The third line contains \(n\) integers \(b_1, b_2, \ldots, b_n\) – how many apples each person received.

Output

In the only line, print Yes if such an exchange could have happened, or No otherwise.

Constraints

\(1 \le n \le 10^5\),

\(0 \le a_i, b_i \le n\).

The scoring consists of the following blocks:

• 1 point for each example from the statement,

• 15 points: \(n \le 4\),

• 20 points: all \(a_i \le 1\),

• 25 points: \(n \le 2000\),

• 38 points: no additional constraints.

You get the points for a block only if your program passes all tests of the block.

Notes

In the first example, the exchange could go like this: person 1 gave an apple to each of persons 2 and 3, person 2 kept one apple and gave one to person 3, and person 3 gave an apple to person 1. Then the people received 1, 2 and 2 apples, respectively.

In the second example, person 1 gave away 2 apples but can keep only one, so the second one must have been received by person 2. However, person 2 received no apples.
