In this exercise you'll be processing log-lines.
Each log line is a string formatted as follows: "[<LEVEL>]: <MESSAGE>".
There are three different log levels:
INFOWARNINGERRORYou have three tasks, each of which will take a log line and ask you to do something with it.
Implement the message function to return a log line's message:
(message "[ERROR]: Invalid operation")
;;=> "Invalid operation"Any leading or trailing white space should be removed:
(message "[WARNING]: Disk almost full\r\n")
;;=> "Disk almost full"Implement the log-level function to return a log line's log level, which should be returned in lowercase:
(log-level "[ERROR]: Invalid operation")
;;=> "error"Implement the reformat function that reformats the log line, putting the message first and the log level after it in parentheses:
(reformat "[INFO]: Operation completed")
;;=> "Operation completed (info)"In this exercise you'll be processing log-lines.
