Yep, vague task description. Basically a word is space + Capital letter. I though i solved the problem untill saw that fixed test xD

ruby:

For ‘abc def’ it expects ‘af1be2cd3’ but the error I am now getting is “Should work for two words, like 'CodeWars Rocks' - Expected: ‘Cs1ok2dc3eo4WR5a 6rs7’, instead got: ‘Cs1ok2dc3eo4WR5as6r’”

Why is ‘CodeWars Rocks’ considered two words, but not ‘abc def’? Is it the capital letters??
