Save your code in SoloLearn and share its link instead. As you can see, big code doesn't fit the limits of characters for a thread's Description, and therefore is truncated.

Edit your Description and paste the saved code link over the truncated raw text code. Add error message description if there was any.

Good luck! 👍
