How to generate the subarray using kadane algo

#1

I need to generate the subarray which has maximum sum . I found out how kadane can give the max sum. but now I have to print the sumarray how it is possible in o(n)

To print the maximum subarray, along with maintaining the maximum subarray sum, also maintain the indices whenever you get maximum subarray sum so far.
The function would be something like this:

int maxSubArraySum(int a[], int size)
{
int max_so_far = INT_MIN, max_ending_here = 0,
start =0, end = 0, s=0;
for (int i=0; i< size; i++ )
{
max_ending_here += a[i];
if (max_so_far < max_ending_here)
{
max_so_far = max_ending_here;
start = s;
end = i;
}
if (max_ending_here < 0)
{
max_ending_here = 0;
s = i + 1;
}
}
cout << "Maximum contiguous sum is "
<< max_so_far << endl;
cout << "Starting index "<< start
<< endl << "Ending index "<< end << endl;
}
