Windowed Average

Given an array of integers and a window size, compute the average of all contiguous subarrays of that size. Each average should be rounded to two decimal places. The input format is as follows: Input: - The first line contains a single integer n (1 <= n <= 10^5) - the number of elements in the array. - The second line contains n space-separated integers, the elements of the array. - The third line contains a single integer k (1 <= k <= n) - the size of the sliding window. Output: - Print the averages of the sliding windows, space-separated, rounded to two decimal places. Example: Input: 5 1 3 2 5 7 3 Output: 2.00 3.33 4.67
