Comprehension Questions

Question	Answer
What did your data structure look like at first? Did this structure evolve over time? Why?	At first my data structure had too many layers, it was a hash stored in a variable called "ride_share_data" with the first and only key being "DRIVER_ID" - I ended up getting rid of both of those and making it a hash of driver IDs stored in a variable called "driver_data" which can be looked and and pretty easily (hopefully) determined that it's ride share data organized primarily by drivers. It was organized primarily by drivers since it seems like most interesting info and most questions were asking about the drivers, so I thought it would make sense to be able to access each driver with the key as the ID in case a specific one was needed to be looked at or named.
What was your strategy for going through the data structure and gathering information?	My strategy was looking at the question, then looking at the data structure and figuring out what layer I would need to access, and then looking at the list of enumerable operators and thinking whether or not I could use one of those to access the answer. Then pseudocoding a solution that included the data structure of the variable that would hold the answer.
What was an example of something that was necessary to store in a variable? Why was it necessary, useful, or helpful?	When determining which driver made the most money, it was helpful to store a hash of each driver (key) and their total earnings (value) so that I could more easily find the highest amount earned and corresponding driver(s) (keys)
What kinds of iteration did you use? Did you use .map? If so, when? If not, why, or when would be a good opportunity to use it?	I used .each, .sum, .select, .uniq, and .map. .map was used after I used .uniq on each driver's array of rides to convert it from an array of rides with unique dates to an array of just dates.
Were some calculations easier than others? Why?	Yes - for some, like the number of rides each driver has given, I just had to get the length of each driver (key)'s array of rides (value) because of the way the whole data was structured, with driver's rides being contained in an array, with the easy to use .length method.
