One thing I don't see how to do without significantly impacting
performance
is to return all offsets if there are overlapping strings. For example:
allOffsets("aba","abababa")
would return 1,5, when it might be reasonable to expect it to return
1,3,5.
Using the offset function with numToSkip would make that easy; adapting
allOffsets to do so would be harder to do cleanly I think.
Can I suggest changing it to "someOffsets()" :-) :-)
But seriously, can you not iteratively run "allofsets" ?
Answer : NO. That doesn't work.
However, there is a more efficient way that does work - but it needs to
be tested before I post it.
