Since it's hard to determine where the Code Lens should be placed for different language, our implementation is just put it for the last line of the code. So as a workaround, you can just add an empty line to your answer.

BTW, an empty line at EOF is recommended actually: https://stackoverflow.com/a/2287990/11620529

The CodeLens will be placed above the tag @lc code=end
