I was trying to solve this problem from ICL2015div2 finals. I understand this is a problem on combinatorics (and perhaps DP) but I could not find a way towards solution.
I am weak in DP problems. They seem overwhelming to me most of the times. An elaborate explanations will surely be helpful for me. :)
Thanks in advance.
