Maximum Average Subarray I · Coding Interview Practice

Maximum Average Subarray IGiven an integer array and an integer k, find the contiguous subarray of length k with the maximum average and return that value.Constraints

n == nums.length

1 <= k <= n <= 10^5

-10^4 <= nums[i] <= 10^4

Examples

Input: nums = [1,12,-5,-6,50,3], k = 4 Output: 12.75

Input: nums = [5], k = 1 Output: 5.0
