Define the queue data structure.
A queue can be defined as an ordered list that enables insert operations to be performed at one end called REAR and delete operations to be performed at another end called FRONT.
A queue can be defined as an ordered list that enables insert operations to be performed at one end called REAR and delete operations to be performed at another end called FRONT.
See lessList some applications of queue data structure.
Applications of the queue are given as follows: Queues are widely used as waiting lists for a single shared resource like a printer, disk, or CPU. Queues are used in the asynchronous transfer of data (where data is not being transferred at the same rate between two processes) for eg. pipes, file IO,Read more
Applications of the queue are given as follows:

What is a binary search? When is it best used?
A binary search is an algorithm that starts with searching from the middle element. If the middle element is not the target element then it checks if it should search the lower half or the higher half. The process continues until the target element is found. The binary search works best when appliedRead more

The binary search works best when applied to a list with sorted or ordered elements.
See lessWhat is a queue? How is it different from a stack?
A queue is a form of linear structure that follows the FIFO (First In First Out) approach for accessing elements. Dequeue, enqueue, front, and rear are basic operations on a queue. Like a stack, a queue can be implemented using arrays and linked lists. In a stack, the item that is most recently addeRead more
A queue is a form of linear structure that follows the FIFO (First In First Out) approach for accessing elements. Dequeue, enqueue, front, and rear are basic operations on a queue. Like a stack, a queue can be implemented using arrays and linked lists.
In a stack, the item that is most recently added is removed first. Contrary to this, in the case of a queue, the item least recently added is removed first.
See lessWhat is a multidimensional array?
If an array has more than two dimensions, it is called a multidimensional array. They are also called an array of arrays. For example, a 3-D array will look like this: int 3darr[10][20][30] – this array can store 10*20*30 elements. Assigning values int ndarr[2][3][5] = {{{1,2,4,5},{5,6,7,9}, {6,5,4,Read more

– this array can store 10*20*30 elements.
Assigning values
int ndarr[2][3][5] = {{{1,2,4,5},{5,6,7,9}, {6,5,4,3}}, {{1,1,3,4}, {2,3,4,6}, {5,6,7,8}}};
Accessing elements
To access each element, we need three nested loops, say i,j,k, so that we can get the value as ndarr[i][j][k]
See lessWhat are the various operations that can be performed on a data structure?
The following are the operations that can be performed on a data structure: Deletion: Deleting an existing element from the data structure. Insertion: Adding a new element to the data structure. Searching: Find the location of an element, if it exists, in the data structure. Sorting: Arranging elemeRead more

How does a linear data structure differ from a non-linear data structure?
If the elements of a data structure form a sequence or a linear list then it is called a linear data structure. Non-linear data structures are those in which the traversal of nodes is done non-linearly. Arrays, linked lists, stacks, and queues are examples of linear data structures, while graphs andRead more
