This article illustrates the method of calculating the continuous maximum subarray sum in C language, which is a very practical technique. Share with you for your reference.
The specific implementation method is as follows:
#include <iostream>
using namespace std;
int array[] = {1, -2, 3, 10, -4, 7, 2, -5};
//int array[] = {-10, -1, -2, -3, -4, -5};
const int size = sizeof array / sizeof *array;
int maxSubArray(int *array, int size)
{
int max = -(1 << 31);
int sum = 0;
int index = 0;
while (index < size)
{
sum += array[index];
if (sum > max)
{
max = sum;
cout << "max: " << max << endl;
}
if (sum < 0)
sum = 0;
index++;
}
return max;
}
int main()
{
int index = maxSubArray(array, size);
cout << "index: " << index << endl;
}
I hope that this paper is helpful to the learning of C programming algorithm design.
