+You may ask why we only rotate right 89 to start the circle. If we start by rotating right then the circle will be off-set by "5" units to the right - we either have to do `right 90` `forward 5` `left 2` then `repeat` for `179`. And finish with another `right 5`. (This means the centre of one of the sides is at the top of the cross - or we can rotate the shape by 1 degree and have it stand on one of it's points)

 ***You are given a set of `$n` integers `(n1, n2, n3, ...)`. Write a script to divide the set in two subsets of `n/2` sizes each so that the difference of the sum of two subsets is the least. If `$n` is even then each subset must be of size `$n/2` each. In case `$n` is odd then one subset must be `($n-1)/2` and other must be `($n+1)/2`.***

 ### Notes:
- * Notice the yoda inequality `$be->[2]>abs $diff` - it makes it clearer that you are only computing the absolute value of `$diff` not that of `$diff < $be->[2]`.
+ * Notice the yoda inequality `$be->[0]>abs $diff` - it makes it clearer that you are only computing the absolute value of `$diff` not that of `$diff < $be->[0]`.
  * `$team1` / `$team2` are refs - so when we update them we make copies `[@{$team2},$next]` rather than pushing to them.
  * We keep the running total as it avoids the need to do the sum each time.
