Finding Average in Sliding Window

You are given an array of integers and a positive integer k. Calculate the average of each contiguous subarray of size k. Input: The first line contains an integer n (1 ≤ n ≤ 10^5), the number of elements in the array. The second line contains n integers, which are the elements of the array. The third line contains an integer k (1 ≤ k ≤ n). Output: An array of floats representing the average of each contiguous subarray of size k. Example: Input: 4 1 3 2 4 2 Output: 2.0 3.0 3.0 (Explanation: The average values are calculated for the subarrays [1,3], [3,2], and [2,4].)
