Question

1. Write a script to read in Roman numbers from the file you saved in #1. Then set delimiter to ‘:’ and save the 10 Roman letters back to file. (You may save the data to a temp file, then copy the temp file back to the original file. Finally, delete the temp file.)

The new data should look something like: I:II:III:IV:V:VI:VII:VIII:IX:X
