“An arcade game player wants to climb to the top of the leaderboard and track their ranking.” So the problem gives you two array (ranked and player). In the player array, you have the points of the player in every round and you have to check his rank based on his score on that round.
- Highest score is ranked 1 and the same score means the same rank.
My problem -> It executes well until it gets over 200k inputs (that means in the case ranked array has +200k smt)
I’ll leave here my code and one of the inputs that I get timeout. I thought I could remember the index I found the player input bigger than the ranked[x] and for the next round score it will start from there and go up. But I couldn’t figure out how to implement it.
