We should be able to create the parking lot with a given size (number of parking spots).That class should consist of variables and methods that simulate how a parking lot works. And to make it a bit more interesting, we will create a small React app that will visualize the workings of our class.įor this challenge, you have to implement a class in JavaScript. In this tutorial we will do that in JavaScript. The Parking Lot is challenge where you are asked to write a class that manages an imaginary parking lot. So, just keep this in mind: when there are 3 slots remaining, 3 variables remaining, and 1 of those variables most go before another, there are only 3 possibilities, and they're worth drawing out, whether it's for a main diagram or a specific scenario.Have you heard about the Parking Lot challenge? If not, let me explain briefly.

However, it more frequently comes up as something you can do for specific scenarios / hypotheticals in both Basic Linear and Advanced Linear games. There have even been cases where it applies to the main diagram for Advanced Linear Logic Games (example: PrepTest 37, Game 2 - page 305 in Next 10). LSAT Logic Games give you scenarios where this technique applies more often than you'd think. (I wouldn't actually number them, of course.) I would just stack those three bolded possibilities into the diagram like this: We can now place C into the empty slots, giving us: These are the only 3 possibilities for the placement of A and B. We can place A and B into the diagram in the following 3 ways: We place A and B first because we know the most about them. We can diagram this as:īecause we have 3 variables remaining, 3 slots remaining, and we know 1 of these 3 (A) is before another of these 3 (B), we know there are only 3 main possibilities for the game. Let's also pretend we have a rule telling us A is before B. We have 3 empty slots, and we have three variables (A, B, C) we haven't placed yet.

Just to keep this short and sweet, let's pretend all the other rules, inferences, and limitations have filled up (determined the placement of variables into) slots (spaces) 1, 2, 6, and 7, giving us: This means we're placing the game's 7 variables (ABCDEFG) in some kind of order. Let's say we're doing an 7-slot / variable Linear game in which only one variable can go in each slot.
