You are given an integer array nums consisting of n elements, and an integer k.
Find a contiguous subarray whose length is equal to k that has the maximum average value and return this value. Any answer with a calculation error less than 10-5 will be accepted.
Examples
Example 1
Input: nums = [1,12,-5,-6,50,3], k = 4
Output: 12.75000
Explanation: Maximum average is (12 - 5 - 6 + 50) / 4 = 51 / 4 = 12.75
Example 2
Input: nums = [5], k = 1
Output: 5.00000
Constraints
n == nums.length
1 <= k <= n <= 105
-104 <= nums[i] <= 104
