Solution: Moving Average from Data Stream

Understand how to implement a MovingAverage class that calculates the moving average of the most recent values from a data stream using a sliding window. Learn to efficiently update values with a queue and maintain a running sum for constant time complexity per operation.

Statement

Given a stream of integers and a window size, calculate the moving average of all integers in the sliding window. Implement a class called MovingAverage that has the following methods:

Constructor (int size): This constructor initializes the object with the specified window size.
double next (int val): This method takes an integer value as input and returns the moving average of the last size values from the stream.

Constraints:

$1 \leq$ size $\leq 100$
$-10^3 \leq$ ...
