Weird array indexing in C#

C# offers a cleaner alternative to traditional array indexing with the caret (^) operator for accessing elements from the end. Instead of using array.Length - 1 for the last element, you can use ^1, with ^2 for second-to-last, and so on. This 'index from end' syntax works with arrays, spans, strings, and other sliceable data structures, providing better performance than methods like .Last().
