Hot Topics Data Structure Introduction to Queue Queue is a linear data structure that is open on both ends and follows First In First Out(FIFO) principle i.e the element inserted in queue at first will be the element removed or popped out of queue at first.For example when we stand in a queue to buy […]
Hot Topics Data Structure Convert Infix to Postfix Problem: Given an infix expression in the form of string str. Convert this infix expression to postfix expression. Infix expression: The expression of the form a op b. When an operator is in-between every pair of operands. Postfix expression: The expression of the form a b op.
Hot Topics Data Structure Stack Using Doubly Linked List Intution: We know stack follow LIFO principle.A node of doubly linked list holds the address of previous node,data of that node and the address of next node.So when the stack is empty and we are inserting the first node we have to point the previous part

Hot Topics Data Structure A linked list is data structure that has two parts, one in which the data is stored and another in which that address of next data is stored.So here we are going to perform the operations of stack using linked list. The head of the linked list is considered to be the
Hot Topics Output: Displaying the elements in stack 1 4 2 3 Top element of the stack is: 1. Deleted element is: 1 Displaying the elements in stack 4 2 3 Top element of stack after removing one element is: 4 Data Structure Stack using Queue Stack is data structure which follows Last In First
Hot Topics Data Structure Stack using array: Algorithm We know stack is a normal array which follows LIFO.So to create stack we will need an array,the size of the array and a variable which will determine the top element of stack. push():To push element into stack we need to make sure that there is atleast

Hot Topics Data Structure What is Stack and Its Operations: Stack As we have discussed in our previous section stack is basically an array which follows LIFO (Last In First Out) principle which is the element inserted first in the stack will be the last element we can take out from stack. We can perform
Hot Topics Data Structure Data structure is a specialized way for organizing and storing data so that user can perform different operations on it. Types of Data Structure Data Structure can be classified into two categories: 1)Primitive: It can only store single datatype 1.Character It can store single character value.The char keyword is used
