Post views by author share
For each published post, return `title`, `views`, and `pct_of_author` — its views as a percentage of that author's total published views, rounded to one decimal. Order by title.
What a strong answer looks like
Say what the query is meant to return before you write it, and name the shape of the answer: how many rows, grouped by what. Then watch the NULLs and the duplicates, because that is where most of these are lost.
Run onlyA query runs as one statement, so there is nothing to step through. Run it and read the rows.
