The stack is a data structure used to store the collection of objects. The object inserted using push and removed using pop operations with last-in-first-out (LIFO) principle.

Stack data structure uses in application function call stack, convert an expression from the different format and more. The image shows the user can remove the stone from the top of the stack and add stone to the top.

Stack section explains how to implement the stack and various application related problems which use stack operation

Data structure problems
1 Stack Implementation
Stack data Structure used to store the objects in last in first out principle (LIFO). Stack implemented using array and in build collection or STL functions
2 Balance symbol
Read the string from user input and validate the symbols in that strings are balanced or not balanced using the stack. Ex {[()]} - Balanced symbol. {(]} - Not balanced symbol.
3 Infix to Postfix
The infix notation places the operators in between the operands. The postfix notation place operators after their operands. Write a program convert from infix notation to postfix notation. Ex Infix (5 + 3) * 12 / 3 Postfix: 5 3 + 12 * 3 /
4 Evaluate postfix or RPN
Evaluate postfix or Reverse Polish notation is a notation in which every operator follows all of its operands. Program to evaluate postfix notation using stack
5 3 stacks in One array
Program to implement 3 stacks using one array.
6 Find in Spans
Find a maximum span of numbers in a given array using stack.
7 Evaluate infix notation using Shunting-yard algorithm
The infix notation place operators in between the operands.write program to evaluate infix expression using the shunting-yard algorithm. Shunting-yard algorithm is a method for parsing mathematical expressions specified in infix notation.
8 Print BST
Print the Binary search Tree using stack.
9 Tower Of Hanoi
Tower Of Hanoi is a mathematical game which consists three rods. The rods have the disk with the different size. The objective of the puzzle is to move the entire stack to another rod.
10 stack sorting
Implement the sorted stack. If the element removed from stack, it should remove maximum priority element.
11 Postfix to infix
Write a program convert from Postfix notation to infix notation using stack. Ex Postfix: 5 3 + 12 * 3 / Infix (5 + 3) * 12 / 3
12 evaluateInfix
The infix notation place operators in between the operands. Write a program to evaluate infix expression using the stack.
13 MyDecimalToBinary
Write a program to convert Decimal number to binary using stack. Get decimal input and print the Binary numbers
14 Reverse String
Write a program to reverse the string using the stack
15 dynamic stack
Write a program for the dynamic stack. If the element reaches the maximum size, extend the stack size and add the element.
16 PostfixtoInfix
The infix notation place operators in between the operands. The postfix notation place operators after their operands. Write a program convert from Postfix to infix
