The function should determine whether there exists any way in which we can split the array into two subarray such that the sum of the elements present in the two subarrays are equal. This output would be much better (see how the values are really close to one another): Find if array can be divided into two subarrays of equal sum in C++. We have to check whether the array can be split into two parts, such that −. Here is an example where I split an array into chunks of 2 elements, simply by splicing chunks out of the array until the original array is empty. Recursively calculate the maximum subarray sum for the left subarray, Recursively calculate the maximum subarray sum for the right subarray, Find the maximum subarray sum that crosses the middle element.
