Question

Write a shell script capable of doing the following:
1. Create a directory "preFinal" in your home directory. In case that such directory exist, rename the existing one into "preFinal.000" and then create empty directory preFinal. While renaming existing preFinal into preFinal.000 you may discover that preFinal.000 also exists, so it needs to be renamed into preFinal.001 and so on.
2. Create empty files "a", "b", "c", etc in directory preFinal in the amount that match the number of directories preFinal*
