Problem 3. Plant Discovery
Здравейте, днес почти цял ден опитвам да реша тази задача, доста време отделих, judge ми да 50/100 и не мога да открия грешката. Реших да изполвам 3 речника, единият за имената на растенията с данни за "рядкост", другият с лист за "рейтинг" и двата с еднакво име за ключ, накрая правя обединяващ речник по техния ключ, за да мога да ги сортирам при отпечаването според условието.
Не знам къде греша, доста ме затрудни задачата и въпреки, че с примерните входoве всичко работи, не мога да открия защо гърмят толкова тестове в judge, ако някой може да помогне, ще ми е много интересно да разбера какво иска judge :)

Problem 3. Plant Discovery
You have now returned from your world tour. On your way you have discovered some new plants and you want to gather some information about them and create an exhibition to see which plant is highest rated.
On the first line you will receive a number n. On the next n lines, you will be given some information about the plants that you have discovered in the format: "{plant}<->{rarity}". Store that information, because you will need it later. If you receive a plant more than once, update its rarity. Check properties.
After that until you receive the command "Exhibition" you will be given some of these commands:
- Rate: {plant} - {rating} – add the given rating to the plant (store all ratings)
- Update: {plant} - {new_rarity} – update the rarity of the plant with the new one
- Reset: {plant} – remove all the ratings of the given plant
Note: If any of the command is invalid, print "error"
After the command "Exhibition" print the information that you have about the plants in the following format:
Plants for the exhibition:
- {plant_name}; Rarity: {rarity}; Rating: {average_rating formatted to the 2nd digit}
…
The plants should be sorted by rarity descending, then by average rating descending
