Climbing the Leaderboard

An arcade game player wants to climb to the top of the leaderboard and track their ranking.

The game uses Dense Ranking, so its leaderboard works like this:

• The player with the highest score is ranked number 1 on the leaderboard.
• Players who have equal scores receive the same ranking number, and the next player(s) receive the immediately following ranking number.

Create a function with the following input parameters, in this order:

• rankedScores: leaderboard scores as an integer list
• playerScores: the scores of the games of the player as an integer list

Returns:

• The player's rank after each new score, as an integer list

Example

playerRank([100, 90, 90, 80], [70, 80, 105])  ➞ [4, 3, 1]

In the above example, ranked players will have ranks 1, 2, 2, and 3, respectively. If the player's scores are 70, 80 and 105, their rankings after each game are 4th, 3th and 1th. Return [4, 3, 1].

Additional Example

playerRank([100, 90, 90, 80], [106, 107, 105])  ➞ [1, 1, 1]
