You are given two integer sequences of length N: a_1,a_2,..,a_N and b_1,b_2,..,b_N. Determine if we can repeat the following operation zero or more times so that the sequences a and b become equal.

Operation: Choose two integers i and j (possibly the same) between 1 and N (inclusive), then perform the following two actions simultaneously:

* Add 2 to a_i.
* Add 1 to b_j.

Constraints

* 1 ≤ N ≤ 10 000
* 0 ≤ a_i,b_i ≤ 10^9 (1 ≤ i ≤ N)
* All input values are integers.

Input

Input is given from Standard Input in the following format:


N
a_1 a_2 .. a_N
b_1 b_2 .. b_N


Output

If we can repeat the operation zero or more times so that the sequences a and b become equal, print `Yes`; otherwise, print `No`.
