Write a function named “make_mult_table” that takes an integer (denoting the max_factor) and returns a vector of vectors of longs representing a multiplication table from 0 to (and including) max_factor.
Example:
max_factor = 3
Return value:
{ {0, 0, 0, 0}, {0, 1, 2, 3}, {0, 2, 4, 6}, {0, 3, 6, 9}, }
