thank you :), it does help. Indeed I didn't read carefully enough

Hello,
I fail to pass a test. It expects ["airplane","apple","air","avenue","airport"], instead got: ["airplane","apple","air","avenue","airport","adamantium","awkwardness","awesome","amazing"]

I tried debugging and saw that the input is 'a'. And displaying all the words starting with 'a' should be appropriate, right? So why does it expect only a part of the array.

Is the test case wrong or am I missing something?
Any help is appreciated.
Thanks
