Basically there's a list of servers that make a particular number of requests each, and also each have a health. The aim is kill all the servers with a certain damage value per hit. Each hit the requests of all the currently running servers are run. Find minimum requests to kill all servers. So say requests array is: [3, 4, 7] and health array: [3, 4, 7] and k (damage) = 3. So you have to see the optimal order of which servers to kill first.
