04. Ununion Lists

Problem:
You will be given a sequence of integers, separated by a space. This is the primal list.
Then you will receive an integer N. On the next N lines, you will receive sequences of integers.
Your task is to add all elements that the primal list does not contain from the current sequence to the primal list
and then remove from the primal list, all elements which are contained in the current sequence of integers.
If there are several occurrences, remove all occurrences you find.
After you are done receiving lists and manipulating the primal list, sort the primal list and print it.
