Introduction: The difference between direct free kick and indirect free kick: The difference between direct free kick and indirect free kick PHP Find the largest continuous sum among any n positive and negative integers: Case description: Write a PHP function. To find the largest continuous sum among any n positive and negative integers, the time complexity of the algorithm is required to be as low as possible; for example: echo getMaxSum(array(-2, 1, 3, 9, -4, 2, 3, 5, -3, -4, 1, 3)); //The maximum continuous sum is (1, 3, 9, -4, 2, 3, 5) The addition function returns 19. The code is as follows:

8. Write a PHP function. To find the largest continuous sum among any n positive and negative integers, the time complexity of the algorithm is required to be as low as possible.

Introduction:: Write a PHP function. To find the largest continuous sum among any n positive and negative integers, the time complexity of the algorithm is required to be as low as possible. ：<?phpheader("content-type:text/html;charset=utf8");//Algorithm analysis: //1. It must be an integer sequence //2. If the entire sequence is not all negative numbers, the largest subsequence One term must be a positive number, // otherwise the sum of the numbers after the maximum subsequence plus the negative number of the first term is definitely not the maximum; //3. If the entire sequence is negative, then the sum of the maximum subsequence Is 0; $arr=array(-2,1,3,9,-4,2,3,8,-
