A question about LeetCode statistics:

I solved a LeetCode question, but my solution is better than only 5% of submissions, which means my solution is not better than 95% of submissions. Should I worry about this as a computer programmer? Does this mean I should write better algorithms? (answer)

Someone asked the following question on Quora: “How long do I have to wait, before I see the answer to a problem in programming?” What do you think it means?

Quora allows anyone to edit a question, and sometimes I edit questions to make them clearer. But in this case a few people had already answered the original question.
