Topcoder SRM 699 Div2 review

Single Round Match 699 Sponsored by Cisco

 

Div II Level One: UpDownHiking

Idea is same with editorial.

 

Div II Level Two: LastDigit

Category: Arithmetric

The approach is different from editorial which uses binary search.

 

Div II Level Three: FromToDivisibleDiv2

Category: Arithmetric, graph

I couldn’t solve it in contest, so I just followed editorial for my practice.
