SUPyF2 P.-Mid-Exam/18 December 2018 - 02. Santa's List

Problem:
Its Christmas time and Santa needs your help with creating the list of noisy kids.
Input
You will receive the initial list with noisy kids each of them separated with "&".
After that you will receive 4 types of commands until you receive "Finished!"
• Bad {kidName} - adds a kid at the start of the list.  If the kid already exists skip this line.
• Good {kidName} - removes the kid with the given name only if he exists in the list, otherwise skip this line.
• Rename {oldName} {newName} – if the kid with the given old name exists change his name with the newer one.
If he doesn't exist skip this line.
• Rearrange {kidName} - If the kid exists in the list remove him from his current position and
    add him at the end of the list.
Constraints
• You won't receive duplicate names in the initial list
Output
Print the list of all noisy kids joined by ", ".
• "{firstKid}, {secondKid}, …{nthKid}"

Input:                  Output:
Peter&George&Mike       Joshua, George, Mike
