Run the programs and compare their execution time and memory requirements. For the execution time comparisons to be meaningful, you must use the same sequence of data across all programs. Start with a dataset of size 10 integers, and increase it by 10x until you reach 1, 10, or 100 million, depending on the amount of memory available on your system. Note that it may not be feasible to use selection sort on data sets bigger than 1 million. So, once the data set reaches 1 million, you may stop the selection sort comparisons, but do continue with the data set size increase for mergesort and radix sort.
