    I wonder why the same algorithm would cost 20ms using c++.

    That's quite interesting. Though my C++ skills are not that great and I don't know the reason, I definitely want to try to do this in C++ and see if I have the same problem.
    Also, sometimes the Leetcode runtimes change if you run your code multiple times. You may want to try to submit this again and see if it still takes 20ms.
