Copy and paste content to markdown

Today I wanted to practice on Leetcode, and then I opened https://github.com/phodal/2md to save the problem to local.
Because I found that there were some small problems with this tool, I forked a copy and fixed some errors that it would generate when converting the content of the leetcode problem.
In this way, copy the problem of leetcode and paste it into my 2md, and then copy the converted markdown to save it locally.

The displayed format is correct, and the effect is much better.
