Problem 1985. How unique?
Sometimes, when we check unique entries of vector we would like to know how many times each value occurs.
Given vector of numbers A return vector U of unique values of A and corresponding vector H with occurrences.
Example:
in: A = [2 2 2 3 3 2 3 8 6 5 6] out: U = [2 3 8 6 5] H = [4 3 1 2 1]
