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!
