Now, if we find any character that have already occurred before, we should consider its last occurrence only (otherwise sequence won't be distinct). For instance, your example produces a suffix tree like: /\ b a | b b b 5 characters in the tree, so 5 substrings. 29, Apr 20. Thus the number of all substrings is the number of all pairs of (not necessary distinct) characters. Count of Distinct Substrings occurring consecutively in a given String.
