Hi @user342,

Firstly, it is against the honour code to share the solution code publicly. Please refrain from doing so.

Secondly, after looking at the code you had shared, your “range” for the “for” loop was incorrect.

Hope this helps. Happy learning!

Thank you for replying me back.
I found the solution, I was only considering unigrams and bigrams and neglected trigrams that is the reason some test cases failed.

Thanks
