Query: A refinement of a result of Andrews and Newman on the sum of minimal
  excludants   We find an interesting refinement of a result due to Andrews and Newman, that
is, the sum of minimal excludants over all the partitions of a number $n$
equals the number of distinct parts partitions of $n$ into two colors. In
addition, we also study $k^{th}$ moments of minimal excludants by means of
generalizing the aforementioned result. At the end, we also provide an
alternate proof of a beautiful identity due to Hopkins, Sellers and Stanton.
