Prepare a notification of the given message which will be displayed on a mobile device. The message is made of words separated by single spaces. The length of the notification is limited to K characters. If the message is too long to be displayed fully, some words from the end of the message should be cropped, keeping in mind that:
- the notification should be as long as possible;
- only whole words can be cropped;
- if any words are cropped, the notification should end with '...'; the dots should be separated from the last word by a single space;
- the notification may not exceed the K-character limit, including the dots.
If all the words need to be cropped, the notification is '...' (three dots without a space).
