Overview

word_play.rb

This gem file contains the ‘Word’ class definition that tests if a given pair of words is an Anagram and if a given word is a palindrome!

Word class. The Word class consists of methods that could be performed on strings, any number of methods can be added. This file consists of two methods named is_anagram? and is_palindrome?.

Summary

This gem can be used to perform two types of tests on string:

  • Use is_anagram? to check if two strigs are Anagram of each other

  • Use is_palindrome? to check if a string is a Palindrome

Example

word1 = Word.new("scream")   # Initialize the class Word
word2 = Word.new("creams")   # Initialize the class Word
is_anagram?(word1,word2)     # Pass 2 words to check if they are Anagram 
is_palindrome("Madam")       # Check if a word is palindrome

Anagram definition:

A word or phraseis said to be an Anagram if rearranging the exact letters would

produce another word. Example: scream and creams

Palindrome definition

A word or phrase is said to be a Palindrome, if we obtain the same word when read from the reverse. Example: “A nut for a jar of tuna”

def is_palindrome?(text) 
  
  if (text.downcase == text.downcase.reverse)
      puts " The word is a palindrome"
      return true
  else
      puts " The words is not a palindrome"
      return false
  end
  
end

.process(text) ⇒ Object

In order to check for *Anagram* convert all the letters into lowercase, split them into letters, sort them and join them to form a string!
