Implement String#reverse and check for palindromes using recursive methods

reverse_and_palindrome_recursion.rb

def reverse(string)
  return string if string.length <= 1
	reverse(string[1..-1]) + string[0]
end

puts reverse("string")
puts reverse("racecar")

def palindrome(string)
	puts string
	return true if string.length <= 1
	string[0] == string[-1] && palindrome(string[1..-2])
end

def palindrome_short(string)
	puts string
	return true if string.length <= 1
	string[0] == string[-1] && palindrome_short(string[1..-2])
end

puts palindrome("racecar")
puts "=========="
puts palindrome_short("racecar")
puts "=========="
puts palindrome("vegas")
puts "=========="
puts palindrome_short("vegas")
