Before this contest started, I have learned and implement the dp optimization IOI 16 Alien Trick. When I see the problem C, I thought this problem can be solved With the Alien trick. Then I started trying to solve the problem and finally I got Accepted verdict. This Problem can be solved simply using sorting the difference of adjacent element. Maximum Contestant has solved this with sorting. When I saw that all Contestant solve this problem very easy way, I became very surprised. But I am happy , because I could apply the trick first day in contest time.
This is my Solution.

Thanks to Everyone.
Please do not be offended but this is so cyan.
this is so purple
Can't argue with that.
This is actually quite cool. I realized that I can compute the minimum of array using Li-chao tree. You can simply make $$$n$$$ lines $$$a_i \times x$$$ and query on point $$$x=1$$$!
You are right. Thank you. ko_osaga

No, what I meant was to leave a comment on contest announcement page that there is an alternative approach to solve this problem.
OK. I will.
Thanks for suggestion.
