Catching up with some old challenges.

With this one I sorted the data by Scroogieness, then split the stream taking the top and bottom 25 records, I then smooshed them back together by joining on record position, created the calculation and sorting by net-scroogieness descending.
Simple.

Nice.

I have two solutions for this one.

The first is a quick solution that matches the "solution browse," however there are only 25 records. Either only have of the people will have a Secret Santa, or each person in a pair will receive a gift from the same person they gave one to which ... isn't very secretive.

So my second solution is a bit longer and required the random and unique tools to ensure we didn't have duplicates *and* that we didn't have someone giving two presents nor receiving two presents.

A bit tougher, but we got there eventually.
