Hello Codeforces Community!

I invite you all to join HackerRank's HourRank 28 on June 3, 2018, at 20:30 IST.

You will be given one hour to solve three tasks. The contest will be rated and the top ten contestants will receive HackerRank T-shirts!

The problems are created by mr.logix, abx_2109, and coderdecode and tested by me.

Good luck and happy coding!

In the second question, the time complexity is of the order 10^8. Does this always run in the time limit on those platforms (Hackerrank & Hackerearth)?

Can someone please help me understand Tourist's solution to the second problem? Link : https://www.hackerrank.com/rest/contests/hourrank-28/challenges/the-most-elegant-sequence/hackers/Gennady/download_solution

I am unable to understand from line 49 onwards, where the actual DP begins. It would be helpful if someone could clarify the logic.
