If someone can help me in this question because I spent more than a week on it

C#

I. Request an input from the user.
A. If the input string is "a", "Q", "quit", "Quit": Exit from loop immediately.
B. If the input string has more than or exactly 3 characters:
1. Call your /Palindrome(..) function and assign the returned value to a local bool type variable.
2. Write if the input string is a palindrome or not to the console.
3. Go back to the beginning of step I.
II. Write an exit message to the console.
static bool IsPalindrome(string value)
// This function evaluates the parameter
// and returns true if the parameter value is a palindrome
// returns false otherwise.
}
Notes:
You shall implement two different loops:
• One for the main loop where the program will repeatedly ask input and decide if it is a palindrome or not.
Another loop for calculating if the value is a palindrome to be implemented in the IsPalindrome(.) function.
•Do not use string.Beverse function, solve the palindrome using a loop.

Useful string Functions:
int Length;
string Substring(int startindex);
string Substring(int startindex, int length);

What I have tried:

I tried more than 10 ways to say that last and I believe it’s time for help
I really want to share what I have tried but because it’s my first question here please don’t make fun of me:)
