+/**
+* @file
+* @brief C++ program for maximum contiguous circular sum problem using [Kadane's Algorithm](https://en.wikipedia.org/wiki/Maximum_subarray_problem)
+* @details
+* The idea is to modify Kadane’s algorithm to find a minimum contiguous subarray sum and the maximum contiguous subarray sum,
+* then check for the maximum value between the max_value and the value left after subtracting min_value from the total sum.
+* For more information, check [Geeks For Geeks](https://www.geeksforgeeks.org/maximum-contiguous-circular-sum/) explanation page.
