a program that reads in a file that contains a list of keys and values. Each line of
the file contains a key and a value, separated by whitespace. Using a Scanner, read the
entire file of keys and values into a map. Then, in a loop, prompt the user with "Key:"
read from the console a key. If the key is present in the file, respond with "Key <key>
has value <value>". If the key does not exist, respond with "Key <key> does not exist.
The user types "Q" to exit the program.
