Simple string filtering algorithm
# During data processing you will face a situation when you will
# need to filter out some data based on string comparison (e.g. process
# only file names which pass some condition). Things get more complicated
# if the condition is meant to be provided by user or as a CLI argument.
#
# Some of the popular methods are following:
# - wildcard matching (e.g. "*.jpg" which will return only jpeg files)
# - regex (e.g. ".*\.jpg")
# - code (e.g. filename.substr(-4) == ".jpg")
