RPOP key [count]

Removes and returns the last elements of the list stored at key.

By default, the command pops a single element from the end of the list. When provided with the optional count argument, the reply will consist of up to count elements, depending on the list's length.

*Return value

When called without the count argument:

Bulk string reply: the value of the last element, or nil when key does not exist.

When called with the count argument:

Array reply: list of popped elements, or nil when key does not exist.

*History
