//According to a research at Cambridge University, it
//doesn’t matter in what order the letters in a word are.
//The only important thing is that the first and last
//letter be in the right place. The rest can be a total
//mess and you can still read it without problem. This is
//because the human mind does not read every letter by
//itself, but the word as a whole.

//Instructions: press the button and scramble the text.
