can someone please answer this code with comments explaining things included! thank you!

(2) (50 points) Implement the function by not allocating a new X 2D array. Hint: Perform the rotation in a layer by Inyer fashion - meaning - dil ferent layers can be processed independently. Also within a layer, you can exchange groups of four elements at a time to perform the rotation Example : Send 1 to 4's location, 4 to 16's location, 16 to 13's location and 13 to l's location. Ungraded but Important : As a comment in your code for Problem 2, write your observation on the different solutioning methods utilized to- day. This week onwards your observation in a course like Data Structures should speak in terms of Time and Space Complexity. Which solution does what in terms of time and space. Which is better, which is worse. Which solution would you prefer and why? Your observation should be no more than 5 lines :)
