Virtual contest is a way to take part in past contest, as close as possible to participation on time. It is supported only ACM-ICPC mode for virtual contests.
If you've seen these problems, a virtual contest is not for you - solve these problems in the archive.
If you just want to solve some problem from a contest, a virtual contest is not for you - solve this problem in the archive.
Never use someone else's code, read the tutorials or communicate with other person during a virtual contest.

standard inputoutput

standard outputJafar has *n* cans of cola. Each can is described by two integers: remaining volume of cola *a*_{i} and can's capacity *b*_{i} (*a*_{i} ≤ *b*_{i}).

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 *a*_{1}, *a*_{2}, ..., *a*_{n} (0 ≤ *a*_{i} ≤ 10^{9}) — volume of remaining cola in cans.

The third line contains *n* space-separated integers that *b*_{1}, *b*_{2}, ..., *b*_{n} (*a*_{i} ≤ *b*_{i} ≤ 10^{9}) — 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).
