To practice more problems feel free to check MYCODE | Competitive Programming at Prepbytes. Hope this blog helps you understand the concept. In particular, we maintain an instance variable n that stores the number of items in the stack and an array items that stores the n items, with the most recently inserted item in items n-1 and the least recently inserted item in items 0. This article tried to discuss the Difference between array, queue and stack. Representing stacks with arrays is a natural idea. In stack, the process of insertion is called push operation and the process of deletion of the element from the stack is known as pop.Īnd, we can easily keep track of the last element using a pointer called top.ĭifference between Array, Stack and Queue Array In LIFO, the element which was inserted last will be the element which was removed first. Stack data structure follows LIFO property i.e.
Stack is a linear data structure in which a user can insert and delete an element from the same end which is known as a top. Peek(): This operation is used to get the value of the element from the front of the queue.
#Java queue to array full#
IsFull(): This operation is used to check whether the queue is full or not. IsEmpty(): This operation is used to check whether the queue is empty or not. Basic Operations of Queue:Įnqueue: This operation is used to Insert an element at the end of the queue.ĭequeue: This operation is used to remove and return an element from the front of the queue. In other words we can say the element that goes in first is the element that comes out first.įor Example A ticket Queue outside a cinema hall where the person enters the queue first will get the ticket first. Generic Queue (Array and Linked List) Implementation Ask Question Asked 6 years, 8 months ago Modified 6 years, 7 months ago Viewed 10k times 1 I am working on brushing up my data-structures knowledge, and was hoping to have my code/thoughts reviewed. name of the array.Ī Queue is a linear data structure. We simply add 1 to the value of back, and then take that number modulo the size of the array, which we call QUEUESIZE. Due to which we can easily calculate the position of each element by adding the memory location of the first element i.e.
An Array is a collection of elements which are stored in a contiguous memory.
