Splet26. feb. 2024 · Your max_crossing_subarray uses two loops which are essentially same but reversed in their direction. In fact you can express it as one function using std::reverse_iterator. Lets refactor a sub function which performs the loop. An Iterator version would look like this: Splet03. nov. 2024 · If the array contains all non-negative numbers, the maximum subarray sum would be the sum of the entire array. Several different sub-arrays may have the same max sum but we need to just return...
Splet11. jul. 2024 · Divide the array in half. For a small array say for size 2 the maximum subarray will be either the left half, or the right half, or the crossing containing both elements for the left half and right half. for eg If arr []= {-3,5} right half is maximum subarray. Splet24. mar. 2024 · Say the maximum subarray consists of two parts — sub-subarray A and sub-subarray B. sub-subarray A is the array from the initial part of the array that consists of all the elements already ...
Splet13. apr. 2011 · brute force algorithm for finding a maximum sum has O (n**3) complexity, see max_sum_subsequence, so it is reasonable to assume that brute force for finding a maximum subarray can't have a better complexity. – jfs Apr 13, 2011 at 15:09 Add a comment 0 As suggested in this answer you can use Kadane's algorithm which has O (n) … SpletI implemented an iterative O ( n) algorithm for solving the maximum sub-array problem. I would like a general review for it. Here the max_subarray is the main function and the ones which are static are auxiliary functions for it. #include int max_subarray (int array [], int *low, int *high); static void initialize (int *sum, int *low ...
