Is it ok that in this challenge you treat ‘aba’ and ‘aba’ as two different strings? It just doesn’t make sense to me. Following that logic I can say that there is no repeating consecutive letters in ‘aab’.


#2

Return the number of total permutations of the provided string that don’t have repeated consecutive letters. Assume that all characters in the provided string are each unique.


#3

There can be consecutive letters in ‘aab’ but the consecutive letters are not from the same index in the string.One ‘a’ is index 0 and the other one is index 1.
