- [ ] Code Katas
- [ ] Find all the unique sequences of digits, like [1, 1, 2, 3, 8] that have the following properties:
Each element of the sequence is a digit between 1 and 9
The digits add to 15
There is at least digit that appears exactly twice
No digit appears more than twice
Order is irrelevant [1, 1, 2, 3, 8] and [1, 3, 2, 1, 8] are the same sequence and only count once.
I believe the original problem did specify that there are 38 sequences that match.
