<prompt> Kutokana na orodha ya idadi, kuendeleza algorithm kupata jumla ya juu ya subarray.  <response>: Heres an algorithm called the Kadanes algorithm that can be used to find the maximum subarray sum of a given list of numbers.1. Initialize two variables max_so_far maximum sum found so far and max_ending_here maximum sum ending at the current position to the first element of the list.2. Iterate over the list of numbers from the second element to the last. - At each iteration, update the value of max_ending_here to the maximum of the current element and the sum of max_ending_here and the current element. - also update the value of max_so_far to the maximum of max_so_far and max_ending_here. 3. The value of max_so_far after the completion of the loop will be the maximum subarray sum.Heres the Python code implementing the above algorithm:pythondef max_subarray_sumnums: max_so_far max_ending_here nums0 for num in nums1:: max_ending_here maxnum, max_ending_here num max_so_far maxmax_so_far, max_ending_here return max_so_farFor example, lets run this on the following input:pythonnums -2, 1, -3, 4, -1, 2, 1, -5, 4printmax_subarray_sumnumsThe output will be 7, which is the maximum sum of the subarray 4, -1, 2, 1.
