You are given an integer array nums consisting of n elements, and an integer k.

\n\n

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.

\n\n

Example 1:

\n\n
\nInput: nums = [1,12,-5,-6,50,3], k = 4\nOutput: 12.75000\nExplanation: Maximum average is (12 - 5 - 6 + 50) / 4 = 51 / 4 = 12.75\n
\n\n

Example 2:

\n\n
\nInput: nums = [5], k = 1\nOutput: 5.00000\n
