Web13 hours ago · Time and Space Complexity. The time complexity of the above code is O(Q*N*log(D)), where Q is the number of queries, N is the number of elements in the array, and D is the highest number present in the array. The space complexity of the above code is O(1), as we are not using any extra space. Web1 day ago · After the iteration, the sub-array with the maximum sum is indicated by the start and end indices, and the size of the sub-array is end - start + 1. Return this value as the result. Note The time complexity of above algorithm to find the maximum subarray sum and its size is O (n), where n is the size of the input array.
