CF392D Three Arrays

There are three arrays $ a $ , $ b $ and $ c $ . Each of them consists of $ n $ integers. SmallY wants to find three integers $ u $ , $ v $ , $ w $ $ (0

The first line contains a single integer $ n $ $ (1

Print a single integer — the minimum possible sum of $ u+v+w $ .

In the first example you should choose $ u=3,v=0,w=2 $ . In the second example you should choose $ u=1,v=3,w=1 $ .
