Why it works, is because for each i, we are trying to find the maximum range starting from i such that the sum of this range is <= k. WebThe basic brute force approach to this problem would be generating all the subarrays of the given array, then loop through the generated subarray and calculate the sum and if this sum is equal to the given sum then printing this subarray as it is the part of our solution. Now we know, An Array with n elements has n* (n+1)/2 subarrays.
