Aurora Serverless can’t scale to zero, that’s bad news for your dev environments! Don’t worry, Neon’s serverless Postgres is here to save the day with instant scaling, predictable performance, and of course, scaling to zero :-D
Problem
By counting carefully it can be seen that a rectangular grid measuring 3 by 2 contains eighteen rectangles:
Although there exists no rectangular grid that contains exactly two million rectangles, find the area of the grid with the nearest solution.
Solution
This problem looks more difficult than it is, I’m not going to go into the details here but basically the number of rectangles inside a x by y grid can be calculated as:
The rest is fairly easy, just pick a range of x and y values you want to try and brute force it!
