• Open problem page in web browser from right-click context menu.

• Intellisense, lint, debug with testcase locally.
  Relative work:leetcode-cli test <filename> --local command fromcpp.run plugin.
  Intellisense and lint service could be provided by other extensions likecpptool. What we should do is to provide some pre-included headers/packages likebits/stdc++.h and someListNode definitions, which has been covered by the effort ofcpp.run plugin.
