A data stack vs queue11/21/2023 If rear=max-1, this condition implies that the stack is full. If top= max-1, this condition implies that the stack is full. If front= -1 or front = rear+1, which means that the queue is empty. If top=-1, which means that the stack is empty. The enqueue operation performs the insertion of the elements in a queue while the dequeue operation performs the deletion of the elements from the queue. It performs mainly two operations, enqueue and dequeue. The push operation inserts the element in a list while the pop operation removes the element from the list. It performs two operations, push and pop. The front pointer holds the address of the first element, whereas the rear pointer holds the address of the last element in a queue. It contains two pointers front and rear pointer. The top pointer holds the address of the last inserted or the topmost element of the stack. It contains only one pointer known as a top pointer. The front end is used for the deletion while the rear end is used for the insertion. It has two ends, i.e., front and rear end. It has only one end from which both the insertion and deletion take place, and that end is known as a top. It follows the principle FIFO (First In -First Out), which implies that the element which is added first would be the first element to be removed from the list. It follows the principle LIFO (Last In- First Out), which implies that the element which is inserted last would be the first one to be deleted. Its structure contains two pointers front pointer and rear pointer, where the front pointer is a pointer that points to the element that was first added in the queue and the rear pointer that points to the element inserted last in the queue. In Queue, the technical words for insertion and deletion are enqueue() and dequeue(), respectively whereas, in the case of the stack, the technical words for insertion and deletion are push() and pop(), respectively. The deletion is performed from another end, and that end is known as a front end. In the case of Queue, insertion is performed from one end, and that end is known as a rear end. A Queue is a structure that follows some restrictions on insertion and deletion. It is an ordered list that follows the principle FIFO (First In -First Out). Dynamic: The dynamic implementation of the stack can be done with the help of a linked list.Ī Queue is a linear data structure.Static: The static implementation of the stack can be done with the help of arrays.There are two ways to implement the stack: We need to allocate the memory to get the size of the stack. To implement the stack, we should know the size of the stack. In stack, the top is a pointer which is used to keep track of the last inserted element.
