Problem 594. "Look and say" sequence
What's the next number in this sequence?
- [0]
- [1 0]
- [1 1 1 0]
- [3 1 1 0]
- [1 3 2 1 1 0]
This a variant on the well-known "look and say" or Morris sequence, where each new iteration is made up by 'saying' the number of numbers you see. That last line is "one 3; then two 1s; then one 0".
Create a function that returns the next element of this sequence, given a vector as a starting seed..

Test suite case 3 seems to be incorrect.
yeah, test case 3 should be [1 1 2 3 1 1 1 5 2 2] by my calculation
Sorry about that. Cut and paste fail.
Test case 3 is still incorrect.
