Not to compete with your brilliant code on optimization, bu I have also written a swap routine that excels especially on numbers close to each other. I know sign function result can be put into a variable, but computers nowadays are so fast... Anyone feel free to use it. static void swap(ref int a, ref int b) { int c = (b - a) ; while (c != 0) { a += Math.Sign(c); b -= Math.Sign(c); c -= Math.Sign(c); } }
