Redis is Database whereas RabbitMQ was designed as a message router or message-orientated-middleware (mom), so I'm sure if you look for benchmarks, you'll find that RabbitMQ will outperform Redis when it comes to message routing.

RabbitMQ is written in Erlang which was specifically designed by the telecom industry to route messages, you get clustering out of the box due to it being written in Erlang which means in a clustered environment, RabbitMQ will outperform Redis even further.

Furthermore, you get guaranteed delivery of messages due to the AMQP protocol, in other words, if the network drops while consuming the message, the consumer won't be able to say thanks for the message, so the consumer will drop the message and Rabbit will requeue the message, if you publish a message and the queue didn't say thanks to the publisher due to network problems or timeouts, Rabbit will drop the message and the publisher will keep on trying to publish the message. You can have publish retries with backoff policies, so

def is_cyclic(input_list):
    """
    The intuition is very simple and can be thought of as traversing a double-linked list or tree-traversals.
    - For the given_list to be cyclic, the first and last chars in words that form the list should match.
    - Which means, these chars should form even pairs.
    
    Thus, this function, 
    1. Creates a new list consisting of only the first and last character of every word in the list.
    2. Convert the new list into a string.
    3. Counts the number of occurences of every character in the new string in step 2.
