Simply compare two sets of lottery combinations and find matched

Objective is to look at each row of unique combination in Group B and check has it matched exactly all combinations in all rows in Group A.

Both sets will have same 5 or 6 or 7 unique number combinations in them.
It can have as many as 200 million rows in each group.

Your program must be able to perform 200 million comparisons within an hour running time.

Then extract those combinations that failed to match.
Save this to an Excel or Notepad format file.

Program language preferred C++ (Ai told me)
