Ruby - Help with select method

Hi,

I have a problem in Ruby that I can't solve, I already tried to google it, but nothing.

I hava an array. I want to use the select method to select tthe elements that contains the string "YES" or the string "NO".

It doesn't work:

a.select { |x| x.include? "YES" || x.include? "NO" }

Can anyone help me?

Thanks!

 

This works

Code:

#!/usr/bin/ruby

a = ["Pradeep","Yes","YES","NO"]

print a.select { |x| x.include?("YES") || x.include?("NO") }

 

Thank you, it works!

It works only with the '(' and ')', and without the white space after 'include?'.
