Plant Discovery Java Fundamentals

Здравейте,

Може ли да ми кажете какво липсва в кода ми? Judge ми дава 87/100 (runtime error).

Условието на задачата е това (02. Programming Fundamentals Final Exam - SoftUni Judge):

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.

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 given plant name 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_name1}; Rarity: {rarity}; Rating: {average_rating}

- {plant_name2}; Rarity: {rarity}; Rating: {average_rating}
…

- {plant_nameN}; Rarity: {rarity}; Rating: {average_rating}"

The plants should be sorted by rarity in descending order. If two or more plants have the same rarity value sort them by average rating in descending order. The average rating should be formatted to the second decimal place.

Input / Constraints

JavaScript: you will receive a list of strings
