Similar String algorithm
I'm looking for an algorithm, or at least theory of operation on how you would find similar text in two or more different strings... Much like the question posed here: http://stackoverflow.com/questions/246961/algorithm-to-find-similar-text, the difference being that my text strings will only ever be a handful of words.

I could easily do this with diff or comm, but I'm not dealing with files and I'd prefer not to output them to files, do the compare and read it back. I see that comm, diff, cmp all allow to pass either two files OR a file and standard input...

The Most Efficient Algorithm to Find First Prefix-Match From a Sorted String Array?
Input: 1) A huge sorted array of string SA; 2) A prefix string P; Output: The index of the first string matching the input prefix if any. If there is no such match, then output will be -1. Example: SA = {"ab", "abd", "abdf", "abz"} P = "abd" The output should be 1 (index starting from 0). What's the most algorithm way to do this ki...
