Sunday common C++ interview problem: Spiral traversal.

Given a grid of size m*n as std::vector<std::vector<int>>, return the elements of this grid in spiral traversal order.

That is, starting at {0,0}, repeat until all elements are traversed:
- advance over columns
- advance over rows
- descend over columns
- descend over rows
