Every March, during the annual NCAA college basketball tournament, which starts with 64 teams and eventually leads to a champion over the course of a month (“March Madness”), other organizations set up similar systems to establish audience favorites/champions in their own worlds. But someone has to set up a bracket of 32 pairs across four “regions” and then figure out how we vote and how the votes are tabulated each time-with winners then being paired against each other. Eventually we get to a “numero uno”!

And before you ask, this is beyond my technical abilities!
