643. Maximum Average Subarray I
Difficulty: Easy
https://leetcode.com/problems/maximum-average-subarray-i/
──────────────────────────────────────────────────
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.
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 <= 10^5
• -10^4 <= nums[i] <= 10^4
