This Code Review question has an accepted answer with a single issue that I wanted to help note/fix.
Then Blindman67 suggested the naive approach with this solution:
This implementation has a small error when given an array with a single high value (e.g. arr = [1,2,33,2,1,1] it returns 2 as the most common number).
How can a user that has a low reputation reach out to a user/community to help correct this answer?
