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..
