    i tried like this but it doesn't show any result
    my@colors=('red', 'cyan', 'yellow', 'blue' ); my @yw_colors = grep {/yw/} @colors;

      UPDATE: Add a print statement. And the regex should be /x|y/, i.e. you want to find an x or an y, not x followed by y. Another possible regex that would work would use a character class: /[xy]/

        i tried but it doesn't work,slightly i change my code then it works that is
        my @yw_colors = grep {/yw/} @colors; ' print @yw_colors,$/
        here we used [] or |.what is the functionality of those symbols please let me know because am a beginner
