fun_string!

gistfile1.rb

Exercise 4

Create a new instance method on the String class called fun_string! which is called on a String object and permanently modifies it by capitalizing the even characters (counting from 1) and then reversing the string. See if you can do it in a single line.

For example,

string = "apples"
string.fun_string!
string # now equals "SeLpPa"

word = "apples"
split_word - word.split('')
split_word.each_with_index do |x, i|
     if i.odd?
     x.upcase!
     end
end
reversed_word= split.word.reverse
reversed_word.join

OR

word = 'apples'
word.split('').each_with_index {|x,i| x.upcase! if i.odd?}.reverse.join
