Custom Sort Order With IComparer

Write a DescendingComparer class that implements IComparer<int> so its Compare method orders numbers from largest to smallest. The tester passes it to List<int>.Sort and prints the result joined by commas. Do NOT write a Main method.

For 3, 1, 2 the program prints the output shown in Expected Output.

Expected Output:

3,2,1↵

= newline. The output ends with a newline — print one after the last line.
