Elements can be added and removed from the Queue from both ends. This general data class has some possible sub-types:An input-restricted deque & an output-restricted deque.
Linked lists are a way to store data with structures so that the programmer can automatically create a new place to store data whenever necessary. Specifically, the programmer writes a struct or class definition that contains variables holding information about something, and then has a pointer to a struct of its type. Each of these individual struct or classes in the list is commonly known as a node.
A circular linked list is very similar to a linear linked list except that it no longer uses null to terminate the list. The tail now points to the head, erasing the need for a null reference. A circular linked list saves the requirement of a head node, but the algorithms of iterating a circular linked list become slightly more complicated.
‘Deleting’ elements from an array might mean two things: deleting the value for a particular index (or indices) in the array (while still leaving the slot in the array open), or, actually removing a slot (and its contents) from the array.
Bubble sort is a simple sorting algorithm. It works by repeatedly stepping through the list to be sorted, comparing each pair of adjacent items and swapping them if they are in the wrong order.
