Get the value of key

Because Redis has a variety of data types, and each type of method differs, all you need to know is the value type stored by key first

You'll need to perform for each key A and depending on the type response perform:

• For "string": Get
• For "Hash": Hgetall
• For "list": Lrange 0-1
• For "Set": Smembers
• For "Zset": Zrange 0-1 Withscores

Keep in mind, hashes and sorted sets you'll be getting the keys/scores and values.
