Write the code in C#

Make a class named program

Make different subclasses for calculator,palindrome,reversestring and superstring

The code should display accurate output

1. Consider a Calculator in C\#. The specifications are as follows: - Addition - Subtraction - Division - Modular divsion - Multiplication - Prime number - Factorial using recursion - Square root of a number 2. Write a program in C\# to check whether a number is a palindrome or not. 3. Write a program in C to reverse a string. 4. A string is said to be a SUPER STRING if the number of times the character appeared in the string is equal to its ASCII value. Given the conditions that the ASCII value of 'A' is 26 and Z is ' 1 '. Example: ZYYZ is not SUPER STRING (As Y appear 2 times and ASCII is 2 but Z 's ASCII is 1 but appeared 2 times). ZYY is SUPER STRING
