Tag lstlisting in polygon codeforces

Revision en1, by SimB4, 2023-06-16 21:23:22

How to insert piece of code in polygon codeforces? Current manual points to the tag lstlisting, However this tag prevents compilation of PDF, while in Edit with preview mode it is displayed correctly. I am getting an error:

"! LaTeX Error: Environment lstlisting undefined."

Tags polygon, statments, latex
