The problem is to find the minimum time to get this job done under the constraints that any painter will only paint continuous sections of boards, say board {2, 3, 4} or only board {1} or nothing but not board {2, 4, 5}.We also know that the values in this range must be in sorted order. The Painter's Partition Problem .

From the above examples, it is obvious that the strategy of dividing the boards into k equal partitions won’t work for all the cases. Will try to explain it in near future.

We can fix the possible low to high range for the target value and narrow down our search to get the optimal allocation.We can see that the highest possible value in this range is the sum of all the elements in the array and this happens when we allot 1 painter all the sections of the board.
A partition like "ababcbacadefegde", "hijhklij" is incorrect, because it splits S into less parts. Don’t stop learning now. S will consist of lowercase English letters ('a' to 'z') only.
