So you have some vector that contains 1's and 0's, and the goal is to return a vector that gives the number of 0's between each one. for example:
Input = [0 1 0 0 0 1 0 1 1 1 0 0 0 1 0 1 1 0 0]
Output = [1 3 1 0 0 3 1 0 2]
My opinion is that the answers for this problem are wrong. The problem is asking for counting zeros between values 1. So for example for Input = [0 1 0 0 0 1 0 1 1 1 0 0 0 1 0 1 1 0 0] the correct Output is [3 1 0 0 3 1 0] and not [1 3 1 0 0 3 1 0 2]. Reasoning that there is no 1 at the beginning and at the end of the vector and so the beginning and end zeros should not be counted.
How about adding a test case in which vector x starts with a 1, such as x = [1 0 0 1 0] ? (Several of the submitted/approved solutions would give the answer as y = [0 2 1] instead of y = [2 1] . )
I was looking for this solution:

but I was not precise enough with the regexp... ;-)
