• There is an old saying: 'work smarter… not harder’. Most of the pudding pairs required to complete the calculations above can be found by considering the ones (units) digit only. You can very quickly eliminate pairs of puddings that can't possibly be candidates for inclusion by only considering the last digits of their weights.
