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. isFull(): If the stack is full, then this function will return a true value or else it will return a false value.isEmpty(): If the stack is empty, then this function will return a true value or else it will return a false value.Like pop(), it returns the value of the topmost element but does not remove that element from the stack. peek()/top(): This function returns the value of the topmost element available in the stack.In the pop() function, we do not have to pass any argument. pop(): It is an operation in which the elements are deleted from the top of the stack.In the push function, we need to pass an element which we want to insert in a stack. push(x): It is an operation in which the elements are inserted at the top of the stack.The following are the operations that can be performed on the stack: ![]() The two operations are performed in LIFO, i.e., push and pop operation. In stack, we can insert the elements of a similar data type, i.e., the different data type elements cannot be inserted in the same stack. It follows the principle LIFO (Last In First Out) in which the insertion and deletion take place from one side known as a top. It is a container that follows the insertion and deletion rule. In case of an array, random access is possible, i.e., any element of an array can be accessed at any time, whereas in a stack, the sequential access is only possible. What is a Stack?Ī Stack is a linear data structure. First, we will look at what is stack and what is queue individually, and then we will discuss the differences between stack and queue.
