Convert a phrase to its acronym.
Techies love their TLA (Three Letter Acronyms)!
Help generate some jargon by writing a program that converts a long name like Portable Network Graphics to its acronym (PNG).
Test suite
require 'minitest/autorun' require_relative 'acronym' # Common test data version: 1.7.0 cacf1f1 class AcronymTest < Minitest::Test def test_basic assert_equal "PNG", Acronym.abbreviate('Portable Network Graphics') end def test_lowercase_words assert_equal "ROR", Acronym.abbreviate('Ruby on Rails') end def test_punctuation assert_equal "FIFO", Acronym.abbreviate('First In, First Out') end def test_all_caps_word assert_equal "GIMP", Acronym.abbreviate('GNU Image Manipulation Program') end def test_punctuation_without_whitespace assert_equal "CMOS", Acronym.abbreviate('Complementary metal-oxide semiconductor') end def test_very_long_abbreviation assert_equal "ROTFLSHTMDCOALM", Acronym.abbreviate('Rolling On The Floor Laughing So Hard That My Dogs Came Over And Licked Me') end def test_consecutive_delimiters assert_equal "SIMUFTA", Acronym.abbreviate('Something - I made up from thin air') end end My answer was:
class Acronym def self.abbreviate(phrase) phrase.split("-").join(" ").split.map(&:chr).join.upcase end end I saw other important answers like those:
- I don't like the scan content because it is hard to understand but it's a short answer.
- I didn't know the
trmethod, it replace the first param with the secound param 🤘
class Acronym def self.abbreviate(string) string.scan(/(\b\w)/).join.upcase end end class Acronym def self.abbreviate(name) name.tr('-', ' ') .split .map { |x| x.slice(0) }.join.upcase end end This was fun!
