WebString Matching The string matching problem is the following: Given a text string T and a nonempty string P, find all occurrences of P in T. (Why must P be nonempty?) T is typically called the text and P is the pattern. We're looking for an exact match; P doesn't contain any wildcards, for example. How efficiently can we solve this problem?
