How to efficiently rotate an array of unknown size in C# using LINQ?

I need some guidance on I'm sure I'm missing something obvious here, but I've been struggling with this for a few days now and could really use some help. I have an array of integers in C#, but the size of the array can vary based on user input. I need to rotate this array to the right by a given number of steps, and I'm trying to figure out an efficient way to do it. I initially attempted using a simple approach involving a loop to manually shift each element, but it seems inefficient, especially for larger arrays. Here's what I've tried so far: ```csharp public int[] RotateArray(int[] array, int steps) { int n = array.Length; steps = steps % n; // In case steps > n int[] rotatedArray = new int[n]; for (int i = 0; i < n; i++) { rotatedArray[(i + steps) % n] = array[i]; } return rotatedArray; } ``` While this works, I recently learned about LINQ and I'm curious if there's a more elegant or performant way to achieve the same outcome using LINQ methods. However, I’m not sure how to handle the case where the steps are greater than the length of the array or if there's a better way to handle very large arrays. Could anyone suggest how I might accomplish this using LINQ? Also, are there any pitfalls I should be aware of when using LINQ in this context? I keep running into performance warnings when testing with larger datasets, which makes me question if LINQ is the right choice here. I'm working on a service that needs to handle this. What am I doing wrong? This is part of a larger API I'm building. Any help would be greatly appreciated! Has anyone else encountered this?
