Explanation:

Here, we created a class Demo that contains two static methods GetSubstrings() and Main().

The GetSubstrings() method is used to find all possible substring based on a given string and then print them on the console screen.

The Main() method is the entry point for the program execution. Here we read a string and then find possible substrings using the GetSubstrings() method.
