You will be given a definition of a task first, then an example. Follow the example to solve a new instance of the task.
In this task, you need to remove all words of a given length in the sentence. The number of letters in a word determine its length, for example, the length of the word "apple" is 5.

Sentence: 'breakfast and a glass of milk is on the table'. Remove all words of length '3' in the given sentence.
Solution: breakfast a glass of milk is on table
Why? Words 'and', 'the' are of length 3. So they are correctly removed.

New input: Sentence: 'the stop sign is on a crooked post in the parking lot'. Remove all words of length '1' in the given sentence.
Solution:
