Horspool string matching
WebMay 22, 2016 · I have coded Boyer-Moore horspool string matching algorithm using node.js. The program works, but always outputs -1, which is what it should output if the pattern string is not in the specified text. I am unable to figure out for the life of me what isn't working, and I would be most appreciative of a hint for what I need to fix.
