At Perplexia Inc Headquarters, the puzzle-writing department has been hugely understaffed as of late. President and CEO, levik, wants the Recruiting Department to hire a number of puzzle-writers, and, to that end, has asked Division Director of Algorithms, Charlie, to come up with a way of determining how many recruiters are needed to focus on hiring new puzzle-writers to reach their hiring goal.

Any given recruiter can be working on filling p positions at once.

Any given position takes d days to be filled by a recruiter.

The hiring goal is to have h new puzzle-writers total, and the goal date to accomplish this is g days from today.

You may assume there are already enough recruiters available; they simply need to be told which position to focus on filling.
