Infected usb drives in mice

I bought a mouse on aliexpress. It was reasonably cheap. It works well enough to be on par with a mouse I can buy here for 4 times the price. I know, this is a well known business model, and those mice are exactly the same.

Yet being bought here or there, how do I figure out whether there is malicious code being executed at the same time I am using it. F.i. a keylogger being run at the same time from the mouse?

Place $k$ cats in a corridor of length $n$ to catch the greatest number of mice

There’s a corridor of length $ n$ divided into $ n$ parts of length $ 1$ . In the $ i$ -th part there are $ a_i$ mice. A cat can be assigned to eat mice from some contiguous segment of the corridor. If a cat was assigned to segment from $ i$ -th to $ j$ -th part then if there are $ s = a_i + a_{i+1} + … + a_{j}$ mices, it will eat $ \max(s – (j – i)^2, 0)$ mice. Your task is to find how many mice can be eaten in total if you can use $ k$ cats. Segments assigned to cats cannot intersect. You don’t have to cover the whole corridor.

This problem appeared on one of my past exams. I’ve tried various approches, including lots of heuristics, dynamic programming and greedy algorithms, but none have worked.
