Wrong Answer in all test cases

#1

I handled the case of circular part and getting correct answer in sample test case but when I submit I get all test cases wrong.
For circular part I take double array;
Example:
1 2 3 4 is the array so I took
1 2 3 4 1 2 3 as my array
Please help me with this if its wrong.

your approach is wrong.
There can be two cases for the maximum sum:

Case 1: The elements that contribute to the maximum sum are arranged such that no wrapping is there. Examples: {-10, 2, -1, 5}, {-2, 4, -1, 4, -1}. In this case, Kadane’s algorithm will produce the result.

Case 2: The elements which contribute to the maximum sum are arranged such that wrapping is there. Examples: {10, -12, 11}, {12, -5, 4, -8, 11}. In this case, we change wrapping to non-wrapping. Let us see how. Wrapping of contributing elements implies non wrapping of non contributing elements, so find out the sum of non contributing elements and subtract this sum from the total sum. To find out the sum of non contributing, invert sign of each element and then run Kadane’s algorithm.
