Maximum length L such that the sum of all subarrays of length L is less than K | Function to return the maximum sum in a subarray of size k.
k must be greater.
Compute sum of first window of size k.
Compute sums of remaining windows by removing first element of previous window and adding last element of current window ..
Function to return the length of subarray Sum of all the subarray of this length is less than or equal to K.
Binary search from l to r as all the array elements are positive so that the maximum subarray sum is monotonically increasing.
Check if the subarray sum is greater than K or not.
Update the maximum length.

How can the above be solved in Python?

=====
Can you provide a code to maximum length L such that the sum of all subarrays of length L is less than K and the other steps required?
