Itinerary

You are building a day planning application. Users will provide a list of expected times for activities and you will determine if they have enough time in the day to fit those activities.

Activities are provided as a keyword lists of times using only :minutes, and :hours.

Given a start time and and end time, your Itinerary should determine if they have enough time to complete all of their activities.

activities = [hours: 2, minutes: 30, hours: 4.5, minutes: 10] # ~430 minutes of activities
start = DateTime.new!(~D[2022-04-24], ~T[12:00:00])
finish = DateTime.new!(~D[2022-04-24], ~T[20:00:00]) # 8 hours or 480 minutes of time

Itinerary.has_time?(start, finish, activities)
true

has_time?/3 should be inclusive, so one hour of activities should fit into one hour of time.

activities = [hours: 1]
start = DateTime.new!(~D[2022-04-24], ~T[12:00:00])
finish = DateTime.new!(~D[2022-04-24], ~T[13:00:00])

Itinerary.has_time?(start, finish, activities)
true

Enter your solution below.

defmodule Itinerary do
  def has_time?(start, finish, activities) do
  end
end
