vector of vector of size code example
Example: how to get size of 2d vector in c++
myVector[
Vector[0, 4, 2, 5],
Vector[1, 4, 2]
];
/*When you call for myVector[1].size() it would return 3 and [0] would return 4.
For the amount of rows (int vectors) in the 2d vector, you can just use myVector.size()
You can run this to see it in actions*/
