When you download the latest version of vim-airline as .zip and unzip it to a temporary directory, you get a vim-airline-master directory in the temp directory. Inside vim-airline-master you'll find autoload, doc and plugin directories.

You should either copy these three directories to your ~/.vim/ if they don't yet exist (don't overwrite existing directories with same names!) or copy the contents of the aforementioned three directories to existing directories under ~/.vim/

# LUNARLOGIC.IO PROGRAMMING TASK

# Imagine we are organizing a Lunar dinner. 
# 30 people have confirmed that they will come.
# We will all be seating at five 6-person tables (A, B, C, D, E, respectively).
# There will be 3 courses. After each course we'll change our seats.
# We'd like every person to sit with as many different people as possible throughout the dinner.
# As a bonus you may think of future similar occasions where different number of people and tables may be available.

# Write a program that would assign 30 people to their seats (A1, A2, A3, etc., up to E6) during each course with that goal in mind.
