// Approval Voting.

// About: https://www.youtube.com/watch?v=orybDrUj4vA
//
// A simple voting system allowing each participant to vote based on whether they approve of each
// option. Voters are allowed to approve of multiple options. The result is the option with the
// most approvals.
//
// Example:
//  //! test [1, 1, 0,   1, 1, 0,   0, 1, 0,   0, 1, 1,   0, 1, 1,   0, 1, 1] => [1]
//
// Output meanings:
//   0: Steak Shack
//   1: Burger Barn
//   2: Veggie Villa
