How to Find Friends
Sophia's drones are not soulless and stupid drones; they can make and have friends. In fact, they already are working for the their own social network just for drones! Sophia has received the data about the connections between drones and she wants to know more about relations between them.
We have an array of straight connections between drones. Each connection is represented as a string with two names of friends separated by hyphen. For example: "dr101-mr99" means what the dr101 and mr99 are friends. Your should write a function that allow determine more complex connection between drones. You are given two names also. Try to determine if they are related through common bonds by any depth. For example: if two drones have a common friends or friends who have common friends and so on.
Let's look at examples:
scout2
and
scout3
have the common friend
scout1
so they are related.
super
and
scout2
are related through
sscout
,
scout4
and
scout1
.
But
dr101
and
sscout
are not related.
Input: Three arguments: Information about friends as a tuple of strings; first name as a string; second name as a string.
Output: Are these drones related or not as a boolean.
Example:
check_connection( ("dr101-mr99", "mr99-out00", "dr101-out00", "scout1-scout2", "scout3-scout1", "scout1-scout4", "scout4-sscout", "sscout-super"), "scout2", "scout3") == True check_connection( ("dr101-mr99", "mr99-out00", "dr101-out00", "scout1-scout2", "scout3-scout1", "scout1-scout4", "scout4-sscout", "sscout-super"), "dr101", "sscout") == False
How it is used: This concept will help you find not too obvious connections with the building of bond networks. And how to work social networks.
Precondition:
len(network) ≤ 45
if
"name1-name2"
in
network
, then
"name2-name1"
not in
network
3 ≤ len(drone_name) ≤ 6
first_name
and
second_name
in
network
.
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
checkio sync
(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
checkio install-plugin --ff
checkio install-plugin --chromium
