How can I sort strings in multiple languages?

Alphabets, strings and languages

• What websites are there out there that are about alphabets, strings and languages? Where could I find a basic website that concerned with computer languages?

  Hello Camillalog, There is a good summary of finite state machines (finite automata) at: http://en.wikipedia.org/wiki/Finite_state_machine which for the three terms you refer to, I can summarize as follows: Alphabet - generally represented as Sigma, is the set of symbols that are accepted by the FSM. For example, a simple FSM accepting binary numbers would have an alphabet of {0, 1}. String - a sequence of symbols. This is explained in a little more detail at http://en.wikipedia.org/wiki/String#Mathematics The above URL should take you directly to the math related definition. Language - the set of strings that are "accepted" by the FSM. When you define the finite automata, you specify one or more accept states. The string is "accepted" if you are in one of those accept states when the FSM is done processing the string. There are a number of other good references on line. Search using phrases such as alphabet string finite automata alphabet string language FSM and similar phrases. For example http://www.cs.appstate.edu/~dap/classes/2490/chap5.html has a number of good examples. --Maniac
