• More test case

Question related to mission Keywords Finder

I feel we need more test case.

  1. easy multiple spaces case. Currently edge test9/9 is the first multiple space case. But it is not easy to find such bug.

    checkio('a  b', 'a b')
  2. multiple keyword in same word case.

    checkio('aaa', 'a')

Another request, I want you to also allows this as an answer like below.

checkio('ab', 'a b') = <snap>a</snap><snap>b</snap> or <snap>ab</snap>
