Hi susan_in_california,
What is the compile line for your project?

It indicates that the copy-constructor for your vector<vector<int>> is
consuming 14.33% of the run time.
That's a lot. Especially if you've taken care not to copy your
vector-of-vectors-of-ints. It appears that you missed a case.
Sincerely,
