http://www.improbable.com/2012/02/17/that-man-kaprekar-and-his-damned-number/ Choose a four digit number where the digits are not all the same (that is, not 1111, 2222, …). Then rearrange the digits to get the largest and smallest numbers these digits can make. Subtract the smallest number from the largest to get a new number, and carry on repeating the operation for each new number. (Don't worry. It'll stop. The Turing tape ends ...) _______________________________________________ Fun and Misc security discussion for OT posts. https://linuxbox.org/cgi-bin/mailman/listinfo/funsec Note: funsec is a public and open mailing list.
