An array of integers, arr[n], can be rearranged arbitrarily. The prefix sum at index iis defined as
psum[i] = arr[0] + arr[1] + ... + arr[i].
8
Rearrange the array to maximize the number of positive elements in the psum array. Report the
maximum number of positive elements that can be achieved in the array psum.
Note: Here, a positive value is defined as an integer value greater than 0.
Example
n = 4
arr = [-6, 3, 4, -10]
One optimal arrangement is [3, 4, -6, -10]. This has an array of prefix sums psum = [3, 7, 1, -9] with 3
positive elements.
Return 3, the number of positive elements in psum. There is no way to have more than 3 positive
elements.
