Changes in kadane's algo

#1

how can we print the max subarray by using kadane’s algo?

@tishya_goyal 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;
}

Hope this helps :slightly_smiling_face:
