Ruby select string from array

Question

I am basically trying to select every string in an array that matches a particular string.

I am currently using the following code, but as you guys know, this only gives an array of the indexes of the elements that evaluate to true. I want the actual string at that position.

arr.each_index.select{|i| arr[i].chars.sort.join == someString}

pls provide sample data

Try this:

arr.select { |s| s == "some string" }

An example:

arr = %w(One Two Three Two Two)

arr.select { |x| x == "Two" }
 => ["Two", "Two", "Two"]
