You counted the boss' offset twice, that's why you had to add it back on. Not a kata issue. Closing.

The description is misleading or there is an error
It is easy to understand that "order doesnt matter" means anywhere in the input string

"Anyone remember life before babies?" in tests expects 1

But there are 2-b 1-a 1-y to make up "baby" in the input string besides "babies" so the test should return 2

better use division because for huge numbers will work for ethernity

Kotlin tests are flawed. I added all (scores minus 5) and twice for the boss.
So that when combined all scores greater than 0 should result to 'Nice Work Champ!'

But didn't pass all tests until added extra 5 to whole group opinion

Parenthesis are unnecessary since && has higher precedence than ||
