Replace first occurrence of pattern in a string [duplicate]
... much better than the regex imho, this is what the regex will eventually do anyway, after skipping overhead. In very long strings with the result very far at the end, the regex impl might be better as it supports streaming the char array, but for small strings, this seems a lot more efficient...
