Can I get assistance with Redis commands that do the following?

commands of Redis to do the following:

1. Store this sentence in a string: “This is Database Systems.”
2. Display the length of the string
3. Add the sentence “The course code is NDBS742” to the end of the string so it reads as “This is Database Systems. The course code is NDBS742.”
4. Automatically delete the string from the database in 60 seconds.
