题目描述

Jafar has nn cans of cola. Each can is described by two integers: remaining volume of cola aia_{i} and can's capacity bib_{i} ( aia_{i} <=<= bib_{i} ).

Jafar has decided to pour all remaining cola into just 22 cans, determine if he can do this or not!

输入格式

The first line of the input contains one integer nn ( 2<=n<=1000002<=n<=100000 ) — number of cola cans.

The second line contains nn space-separated integers a1,a2,...,ana_{1},a_{2},...,a_{n} ( 0<=ai<=1090<=a_{i}<=10^{9} ) — volume of remaining cola in cans.

The third line contains nn space-separated integers that b1,b2,...,bnb_{1},b_{2},...,b_{n} ( ai<=bi<=109a_{i}<=b_{i}<=10^{9} ) — capacities of the cans.

输出格式

Print "YES" (without quotes) if it is possible to pour all remaining cola in 22 cans. Otherwise print "NO" (without quotes).

You can print each letter in any case (upper or lower).
