Sorry if this has been posted
Under the Deque section, the last sentence in the second paragraph.
Just like the Array, you can call append to add elements to the Deque, or remote(at:) to remove a specific element at some index.
should be remove(at:)
Once again sorry if this has been posted, i did a quick glance in the forum and I didn’t see this mentioned so I thought I should just post it
