I am looking in a long string of the sort:

aaaabdbbdaccdacdaaabdcd...

and thus want to know the number of occurrences of any of the substrings of size 3 (as in the example). Sure, I could leave out the ones which are zero, don't need them. But I thought that I will have to loop over all possible substrings of size 3 anyway and count their occurrences.
Thanks,
Hadassa
