Given a row vector of integers with repeating values (with all repeating values occuring in a single continuous run), create an array that is the cumulative count of the unique values -
%% Example 1
input = [4 5 5 6 11 11 11 11 20 20 20 20 20 20 20 35 50 50];
output = [1 1 2 1 1 2 3 4 1 2 3 4 5 6 7 1 1 2];
%% Example 2
input = [33 33 33 22 22 11];
output = [1 2 3 1 2 1];
Only vectorized solutions will be accepted. Check the test suite for banned functions.

Cool problem! For the benefit of those who have yet to solve it, you don't need to "remember" the counts of each element, so [4 5 5 6 5 5] should yield [1 1 2 1 1 2] and not [1 1 2 1 3 4].
Thank you Christian!
FYI - Such cases aren't included in the scope of this problem.
I have updated the Problem description to make the statement more precise.
Though they will be considered for upcoming variations of this problem!
Thanks, Duyman. I have a solution for that case too. Unfortunately submitting problems to Cody appears to be broken right now, which I only realized AFTER creating a new one.
