Daily Challenge 295 - Sort Leaderboards
In this challenge, you'll be given a leaderboard in the form of an array, as well as a list of strings. Using the information in the list, sort the leaderboard.
Example
array:
['John', 'Brian', 'Jim', 'Dave', 'Fred']
list:['Dave +1', 'Fred +4', 'Brian -1']
The steps for our example would be:
# Dave up 1['John', 'Brian', 'Dave', 'Jim', 'Fred']# Fred up 4['Fred', 'John', 'Brian', 'Dave', 'Jim']# Brian down 1['Fred', 'John', 'Dave', 'Brian', 'Jim']
Then, we return the completed leaderboard:
['Fred', 'John', 'Dave', 'Brian', 'Jim']
Strings will never ask you to move a name higher or lower than possible. The strings in the list will always be a name in the leaderboard, followed by a space and a positive or negative number.
Tests
leaderboardSort(['John', 'Brian', 'Jim', 'Dave', 'Fred'], ['Dave +1', 'Fred +4', 'Brian -1'])
leaderboardSort(['Bob', 'Larry', 'Kevin', 'Jack', 'Max'], ['Max +3', 'Kevin -1', 'Kevin +3'])
Good luck!
