Climbing the Leaderboard

Problem Statement :

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.

ranked = [100, 90, 90, 80]
player = [70, 80, 105]

The 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, 3rd and 1st. Return [4, 3, 1].

Function Description

Complete the climbingLeaderboard function in the editor below.

climbingLeaderboard has the following parameter(s):

int ranked[n]: the leaderboard scores
int player[m]: the player's scores


int[m]: the player's rank after each new score

Input Format

The first line contains an integer n, the number of players on the leaderboard.
The next line contains n space-separated integers ranked[i], the leaderboard scores in decreasing order.
The next line contains an integer, m, the number games the player plays.
The last line contains m space-separated integers player[j], the game scores.

1 <= n, m <= 2 * 10^5
0 <= ranked[i], player[j] <= 10^9  for 0 <= i, j < n
The existing leaderboard, ranked, is in descending order.
The player's scores, player, are in ascending order.

Find the Running Median

The median of a set of integers is the midpoint value of the data set for which an equal number of integers are less than and greater than the value. To find the median, you must first sort your set of integers in non-decreasing order, then: If your set contains an odd number of elements, the median is the middle element of the sorted sample. In the sorted set { 1, 2, 3 } , 2 is the median.

Minimum Average Waiting Time

Tieu owns a pizza restaurant and he manages it in his own way. While in a normal restaurant, a customer is served by following the first-come, first-served rule, Tieu simply minimizes the average waiting time of his customers. So he gets to decide who is served first, regardless of how sooner or later a person comes. Different kinds of pizzas take different amounts of time to cook. Also, once h
