Itinerary

You are building a day planning application. Users will provide the time it takes to complete an activity in minutes and you will determine if there is enough time to fit the activity between two DateTimes.

Example Solution

defmodule Itinerary do
  def has_time?(start, finish, minutes) do
    DateTime.diff(finish, start) >= minutes * 60
  end
end

Implement the Itinerary module as documented.

defmodule Itinerary do
  @doc """
  Given a number of minutes, determine if there is enough time 
  between two `DateTimes` to fit an activity lasting a number of minutes.

  ## Examples

    iex> Itinerary.has_time?(~U[2020-01-01 12:00:00Z], ~U[2020-01-01 12:01:00Z], 1)
    true
    
    iex> Itinerary.has_time?(~U[2020-01-01 12:00:00Z], ~U[2020-01-01 12:10:00Z], 10)
    true

    iex> Itinerary.has_time?(~U[2020-01-01 07:00:00Z], ~U[2020-01-01 08:00:00Z], 60)
    true

    iex> Itinerary.has_time?(~U[2020-01-01 12:00:00Z], ~U[2020-01-01 12:30:00Z], 31)
    false

    iex> Itinerary.has_time?(~U[2020-01-01 07:00:00Z], ~U[2020-01-01 08:00:00Z], 61)
    false
    
  """
  def has_time?(start, finish, minutes) do
    total_available_time = DateTime.diff(finish, start, :minute)

    minutes <= total_available_time
  end
end
