Problem 2403. Best Square-Shaped Grid for Subplot

hello Ned. if you have 5 plots 3*2 grid subplotting will look better. similarly if x = 11, 4*3 subplot will look better shape. for some instances m=n for some not. thats the tricky part of the question :)

I imagine that you could more precisely define what the "optimum" solution you are after is by saying something along the lines of "the solution that leaves the least empty plots while keeping the difference between the number of rows and columns to 1 or less"?

Alfonso you're right. The optimum word could have been elaborated like that. I appreciate your effort.
