Nowadays the drones are working in transportation. ( Delivery drone(Wikipedia) ) Let's make a plan to ensure the efficient drone movement.
The input value is a list of integers. One or more numbers of this list represent the existence of the package(s) to be transported and its destination. You have to return the shortest moving distance for the drone to complete all transportation as an integer.
- The drone is initially at position 0 (far-left position).
- The drone can carry only one package at a time.
- You can drop the package only at the destination point.
- You aren't forced to pick up the package at the destination point.
- The drone returns to position 0.
delivery_drone([0, 2, 0]) == 4 delivery_drone([0, 0, 1, 2]) == 6
Input: The information about the packages (a list of integers).
Output: The shortest moving distance (an integer).
- 3 ≤ len(input) ≤ 30
- 1 ≤ number of packages ≤ 9
CheckiO Extensions allow you to use local files to solve missions. More info in a blog post.
In order to install CheckiO client you'll need installed Python (version at least 3.8)
Install CheckiO Client first:
pip3 install checkio_client
Configure your tool
checkio --domain=py config --key=
Sync solutions into your local folder
(in beta testing) Launch local server so your browser can use it and sync solution between local file end extension on the fly. (doesn't work for safari)
checkio serv -d
Alternatevly, you can install Chrome extension or FF addon
checkio install-plugin --ff
checkio install-plugin --chromium
