We can construct meaningful derivation trees that enable us to represent arithmetic expressions in infix, prefix and postfix forms. A binary tree is enough to represent all these three notations of arithmetic expressions. Both prefix and postfix notations are unintelligable for humans. But they are of great use in computer science. Compilers often convert infix to prefix notation and then to assembler code. From a derivation tree of an algebraic expression, we can get equivalent prefix and postfix notations. An algebraic expression in terms of operators and operands can be derived by an ambiguous context-free grammar. Prefix notation is the parenthesis-free notational scheme invented by Polish logician Jan Lukasiewicz and is often called polish notation. In prefix notation operators are followed by operands.
For example, in prefix notation A + B is written as +AB. Postfix notation is reverse of prefix notation. AB+ is the equivalent postfix notation of A + B. The infix form is evaluated and the binary tree is created according to the priority of the operators. Let us start from the simplest examples.

Linear Search in C and C++ Languages
Linear search simply means 'looking for an element in the whole array from one end to the other'. The searched element is compared with the first element of array first, then with the second, then with the third, so on upto the end of the array. This is time consuming when the array is pretty enough. The time complexity is highest.The C and C++ programs for linear search is given below.
C Program:
C Program:
#include<stdio.h> void main() {
C and C++ Programs to Check Whether a Number is Strong Number or Not
This post contains C and C++ program to check whether a given number is Strong number or not. A strong number is a number for which the sum of factorials of its digits is equal to the number itself. The first one is C program to check whether the input number is a strong number or not. An example is 145. 1!+4!+5!=1+24+120=145 Therefore 145 is a strong number.
C Program:
C Program:
#include<stdio.h> long int factorial(int n) {

How To Make a Text Subscript or Superscript Using HTML Code
To make a text superscript or subscript in a webpage using HTML language, there are two tags provided in the language.
Superscript
To make a text or some characters superscript, the HTML tag <sup> is used. For example, suppose we have to display 2n+1. To display it, we have to use the following code:
2<sup>n+1</sup>
We have to enclose the characters to be made superscript in <sup> and </sup>
