Talk:Best shuffle

This was a fun algorithm to write --- lots of twists and turns. Gerard Schildberger

Task Description

I think it would improve the task description if we said something along the lines of "Shuffle the characters of a string to produce a string as different as possible from the original. That is, the maximum # of characters in the output differ from the characters at the corresponding positions at the input". Only more concise :). I say that because the current wording lends itself to a trivial solution - reversing the string (because it doesn't make clear that a "character" is different only if its value, not its index, is different). In fact, that's how I initially interpreted the task (character=index), until I saw the solutions were a lot more complex than reverse().
