/*
 *  pairwise takes an array of numbers and a target number as arguments, and

 *  Caveats:
 *  - Each index can only be used once
 *  - Given a choice between two indices that can pair to the target, the
 *    lowest index should be used. For example, passing ([5, 6, 6], 11) to
 *    pairwise, the resulting sum should be 1, since index 0 (the 5) and
