Sport Cards Task
The task:
You will receive several input lines in one of the following formats:
"{card} - {sport} - {price}"
"check {card}"
The card and sport are
strings. Price will be a floating point number. You need to keep track
of every card. When you receive a card, a sport and a price,
register the card in the database if it isn't present, otherwise add
the sport and the price. If the card already contains the sport, you
need to overwrite the price. If you receive"check {card}"you need to
check if the card is available or not and print it on the console in
the format:
"{card} is available!"if the card is present and
"{card} is not available!"if the card is not present
You should end your program when you receive the command
"end". At that point you should print the cards, ordered by sports’ count in desecending order. Foreach card print their sport and price ordered by sports’ name.
