We usually use arrays to implement queues in Java and C/++. In the case of Python, we use lists. Python Java C C++ # Queue implementation in PythonclassQueue():def__init__(self, k):self.k = k self.queue = [None] * k self.head = self.tail =-1# Insert an element into the ...
Queue Implementation in Python, Java, C, and C++ In Java and C++, queues are typically implemented using arrays. For Python, we make use of lists. C C++ Java Python #include <stdio.h> #define SIZE 5 voidenQueue(int); voiddeQueue(); voiddisplay(); intitems[SIZE], front = -1, rear...
This package provides a drop-in replacement for the Python multiprocessing Queue class which handles transport of large numpy arrays. It avoids pickling and uses the multiprocessing Array class in the background. The major difference between this implementation and the normal queue is that the maximal...

int size(): to get the number of elements in the Set. boolean isEmpty(): to check if Set is empty or not. boolean contains(Object o): Returns true if this Set contains the specified element. Iterator iterator(): Returns an iterator over the elements in this set. The elements are ret...
