Problem 790
Posted: Sun Mar 20, 2022 6:52 am
This may be a dumb question, but what is the definition of "grid square"? I'm picturing like a sheet of graph paper with lines at integer values of x and y and the smallest possible squares with integer coordinates. For example, $3\le x\le 4$ and $20\le y\le 21$ would be a grid square. However, if that were the case, there would be fewer than 196 clocks in the example interval.
196 seems to suppose each coordinate is a grid square, like $(4,20)$ contains a clock. So this I assume this grid would be more like a spreadsheet with each box having one set of (x,y) coordinates?
