It is simple to construct the optimal prefix code in binary: A = 0, B = 10, C = 11. Then, a message is encoded as ABC -> 01011. We see that an equivalent method for performing the encoding is as follows: Start with number 1, and perform an operation on the number for each input letter.
Toward this end, this WikiProject identifies, gathers, and rates all articles about JavaScript. It also identifies, gathers, and creates redirects to all article sections about JavaScript (for example, the links Comment (JavaScript) and Comments in JavaScript redirect to Comment (computer programming)#JavaScript).
