Solution: Moving Average from Data Stream
Explore how to implement a MovingAverage class in C++ that calculates the moving average of integers from a stream within a sliding window. Understand using a queue for recent values and maintaining a running sum to achieve constant time complexity for updates and retrievals.

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
sizevalues from the stream.
Constraints:
