I was trying to solve jelly from last year(and this year) practice contest. First 4 subtasks are very easy but i don't have any idea about the last 2 subtasks. Can anyone share their solution.
Thank you in advance.
Current Progress: (if it matters)

I was hoping that there's a greedy for the full solution since constraints seemed too big for dp. But looking at submissions from oj.uz there seems to be a dp solution. On greedy, i tried to always use the shop with highest money and failed.
