(15 points) Write a Python code to implement your algorithm described above with following data: Read the integers from rand 1000000.txt of HW2. Split it into 100 rand 10000 lists. Feel free to use your own file naming convention of those sub-lists for easier save and read operations Sort 50 sublists with radix sorts with counting sort as underlying sort for each digit Remaining 50 sublists with bucket sorts Finally merging the 100 sorted sublists into one sorted list using the algorithm you specified above.
