GoKawiilDeveloper explains the bitap string-matching algorithm's bitwise elegance
A technical blog post walks through how the bitap (shift-and) algorithm finds a pattern inside a text, building it up step by step from the naive brute-force matching approach. The author shows how the method can be adapted to process text as a stream of characters rather than requiring the whole string in memory, and highlights its use of bitwise operations for efficiency when the search pattern is shorter than a machine word.
