Title: Fixed result type of the words function and tests

Fixed result type of the `words` function and fixed test coverage.
`words(0)` should return an array with one word, `"0"`, as in the case of running `words(123)` we had `["123"]`, but we had an empty string `""`.
Also `words("")` returns `""`. But with clean string `words(" ")` return `[""]`. Magic)
Also fixed tests of `trim`.
