For Ruby -> Collection -> Letter frequency counter

how can we make it so it will print / puts only the letters that exist in the phrase and not all the alphabet? what if statement shall we use? i thought and tried something like the one that has the question following this lesson but it didn't work. thanks to whom ever will help. :-)
