Let's consider that we have two teams, A and B. Let's say that A wins the playoff by winning three games out of the five possible. So, when we write A, it means that team A won the game, and when we write B it means that team B won the game. So the options will be:

AAA , AABA , ABAA , BAAA, ABBAA , ABABA , BAABA , BBAAA , BABAA , AABBA

The options above will be exactly the same if B wins the playoff. In this case, we will have:

BBB , BBAB , BABB, ABBB , BAABB , BABAB , ABBAB , AABBB , ABABB , BBAAB
