Depending on your language, stack may not be supported natively. You may simulate a stack by using a list or deque (double-ended queue), as long as you use only standard operations of a stack. You may assume that all operations are valid (for example, no pop or peek operations will be...
Queues typically, but do not necessarily, order elements in a FIFO (first-in-first-out) manner. Among the exceptions are priority queues, which order elements according to a supplied comparator, or the elements' natural ordering, and LIFO queues (or stacks) which order the elements LIFO (last...

Unlike other java queuing solutions, messages are not lost when they are read with a tailer. This is covered in more detail in the section below on "Reading from a queue using a tailer". To write data to a Chronicle Queue, you must first create an appender: try (ChronicleQueue queue =...
Due to this property, dequeue may not follow the first in first out property. Queue implementation using Array: For the implementation of queue, we need to initialize two pointers i.e. front and rear, we insert an element from the rear and remove the element from the front, and if we ...
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 = -1; ...
