WebFeb 19, 2024 · As for the brute_match algorithm, this is the algorithm that you describe. Python's string splicing does not allow for out of index bounds errors, so if we have a = 'abc', then a [2:100] is STILL just 'c'. So i was abusing that nice convention. But the brute force algorithm is doing just that. – jlarks32 Feb 19, 2024 at 22:30 Hey, thanks again.
