Question

I want to reverse all the words in a string such that

1. Orders of the words should not be change
2. Number of blank spaces in the words should be remain the same

For Ex:- When my string is "How     Are  You" it should return "woH     erA  uoY"

I tries something like following

def reverse_string(str)
  arr = str.split(" ")
  new_arr = arr.collect{|a| a.reverse}
  new_arr.join(" ")
end

But it will not work for the strings which may have multiple blank spaces between the words.

Answer 1

s = "How     Are  You"
s.gsub(/\w+/) { |match| match.reverse }
