Inversion of array for circular

int maxCircularSum(int a[], int n)
{
// Case 1: get the maximum sum using standard kadane’
// s algorithm
int max_kadane = kadane(a, n);

// Case 2: Now find the maximum sum that includes  
// corner elements.  
int max_wrap = 0, i;  
for (i = 0; i < n; i++)  
{  
        max_wrap += a[i]; // Calculate array-sum  
        a[i] = -a[i]; // invert the array (change sign)  
}  
  
// max sum with corner elements will be:  
// array-sum - (-max subarray sum of inverted array)  
max_wrap = max_wrap + kadane(a, n);  
  
// The maximum circular sum will be maximum of two sums  
return (max_wrap > max_kadane)? max_wrap: max_kadane;  

}

 // max sum with corner elements will be:       // array-sum - (-max subarray sum of inverted array)       max_wrap = max_wrap + kadane(a, n);
 // max sum with corner elements will be:       // array-sum - (-max subarray sum of inverted array)       max_wrap = max_wrap + kadane(a, n);    CAN YOU PLEASE EXPLAIN THIS PART FROM THE ABOVE FUNCTION?

what is ur doubt??
what do u want to understand

It isn’t accepting all the test cases. Where is the error???
