Using visual studio (C#)  create a program, name it
PRGYOURNAMEFA1,
 that implements a search and replace function recursively. Your program should allow a user to enter
 a string
 ,
a substring
 to be replaced in the entered string and a
character/s
 to replace
the found substring




Program Structure


1. A main class that implements the logic of the program – name this class
TestSearchReplace


2. Add a class named
SearchReplace
 to the main class with two methods, including:
a.
SearchSubstring()
- return method
b.
ReplaceSubString()
 - void method

The two method should be called using an object in the main class.
DONT CREATE  THE TWO METHODS IN THE MAIN CLASS




Sample Output
