Sorting...

Ever thought about how computers do sorting? I came across a very good YouTube video that explains it very well in the form of my wee doodle here. Basically compares 2 numbers at a time in a waterfall sequence. In each box, big number goes forward, small one drops down.

I stored it under interesting but not likely to be used knowledge until I came across a puzzle that required the sequence exactly.

Not the most efficient solution (yet!) but it got the desired result that's been eluding me for months.
