#1Read in a positional argument and store it in a variable named FILE.

#2Create an if branch that checks to see if FILE points to a file that exists or not. If the file exists, have the script print out the message "[FILE] exists!" where [FILE] is filled in with the actual filepath. If the file does not exist, have the script print out the message "[FILE] does not exist!]" where [FILE] is filled in with the actual filepath.

#3Create a loop that reads in the file that was passed in and stored as FILE and print each line one at a time to stdout.
