You have to initialize ms and cs with 0 and not with ar[0]…Also you are not printing the result in your code. After printing result for each test case you have to add an endl.

For any doubt with the concept, you can refer this:

Maximum Circular Subarray Sum (Editorial)

So if we subtract the negative value of this new sum from the cumulative sum of the original array we will get another candidate for the answer and name it candidate2. MY DOUBT IS WHY array-sum - (-max subarray sum of inverted array) WHY NOT array-sum - (max subarray sum of inverted array) Because its the minimum of original array.
