Comprehension Questions

Question	Answer
What did your data structure look like at first? Did this structure evolve over time? Why?

• My data structure took some time to organize. I initially didn't have a ride_share array containing all data as I immediately split each driver into hashes. After a few iterations I organized the data structure based on the information that I needed to pull from the hashes/array.

| What was your strategy for going through the data structure and gathering information? |

• My strategy ( quite foundational) was to go through each layer of the data and figure out a way to pull the information from the array/hashes. My next strategy would have been to organize the information utilizing more sophisticated methods learned in class.

  |
  | What was an example of something that was necessary to store in a variable? What was the scope of each of that variables? Why? | |

• I need to store the data from each driver/per day into a variable. For example, In order to calculate total cost for each driver, I created several variables to capture the cost per driver/day. This variable further served to be part of the addition of each's day earnings.

| What kinds of iteration did you use? Did you use .map? |

• I am not comfortable yet using .map and need to work on it with my classmates or instructor or tutor. Although I am familiar with .map's function (equivalent to each.do), I am still having a bit of challenge applying it to my codes.

| Were some calculations easier than others? Why? | |

• Most calculations were straigntforward because of a well organized data structure. It was clear where to pull information that would contribute to the desired calculations.

I am aware that I did not complete the assignment fully utilizing the tools given. I will go over it with my tutor today and a few classmates - compare/contrast various tools utilized and learn from the process.

Thank you!

You created a good structure for the data, but your calculations were not methods and they used hard-coded values for the driver ids and dates instead of using loops and enumerables to do the work without having to know specific driver IDs and dates. So a good start, but you need to work on creating methods that work on that structure regardless of the specific values.

[CheezItMan]

This works, but you need to calculate the number of trips programatically not by hard coding the specific driver IDs and dates

[CheezItMan]

This is similarly calculating the costs by hard-coding the driver ids and dates.

[CheezItMan]

This might work better as a method that returns the driver costs.

def driver_costs(data)
  return data.keys.map do |driver_id|
    driver_totals = {id: driver_id}
    total = 0
    data[driver_id].keys.each do |date|
      total += data[driver_id][date][:trips].sum do |trip|
        trip[:cost]
      end
    end
    driver_totals[:costs] = total
  end
end
