JFF1: Exchanging the values of two variables
Abstract
The problem of exchanging the values of two variables without using additional variables is very well-known. Most presentations, however, rarely highlight the properties on which the solution depends. In this short note, we investigate these properties, in order to generalize and better understand the problem.
