Comprehension Questions

Question	Answer
What did your data structure look like at first? Did this structure evolve over time? Why?	My data structure actually didn't change too much over time. I think this was because I made a preemptive effort to look at what the program was supposed to do and decided to store my data accordingly.
What was your strategy for going through the data structure and gathering information?	I tried to see which part of the data seemed more fitting for a hash (like having multiple information related to one item) or an array, where I could just list a series of items that were similar. In this case, all the drivers had drives, so it seemed fitting to put them in an array. Each driver had multiple drives, so that could be an array, but each drive had information about rider, cost, rating, etc, so it was more fitting to store that in a hash.
What was an example of something that was necessary to store in a variable? Why was it necessary, useful, or helpful?	To calculate the total amount of money each driver made, that value had to be stored in a variable. Because the value was changing with each iteration (adding the price of the next drive), storing in a variable seemed the most effective method to hold the previous value, add to it, and eventually print it.
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 only ".each" iterations in this code. I spent some time trying to use the ".map" iteration, but I was having difficulty getting the program to store and print the data properly. I think it's better to use the ".map" iteration when you are storing a different value in the same array or hash size, and need to print out those values. In this program, I feel every portion could have found the ".map" iteration helpful, especially in finding the highest or lowest value.
Were some calculations easier than others? Why?	I found the calculations that asked to output the driver who made the most money and the driver with the highest average rating were the hardest. For these portions, not only did I have to calculate the values to compare among the drivers, I had to compare the values and store the "winning" driver in a separate variable.

You have these arrays grouped by driver, but chose to leave the data inside these hashes, even though it's redundant. When I see groupings like this, it makes me think the outermost layer should probably be a hash!
