some simple approaches can also be very effective. The following is one of them. Assume that A‚ B‚ C‚ D‚ E are 5 variables storing 5 numbers respectively; and we would like to show the numbers on the screen in descending order. It can be done using the procedure as follows. 1. 2. 3. 4. 5. Initialize a variable number F that keeps a very large value (must be larger than those values of A‚ B‚ C‚ D‚ E) Search among the batch for the biggest number‚ which is smaller than the value of F Show
