Given a stream of integers and a window size, calculate the moving average of all integers in the sliding window.
|
|
|
|
Implement the MovingAverage class:
|
|
|
|
MovingAverage(int size) Initializes the object with the size of the window size.
|
|
double next(int val) Returns the moving average of the last size values of the stream.
