|You have a rectangular piece of paper that's divided into 1x1 cells, each of which has an integer value. The paper will be described by a String paper. The ith element of paper will be a space delimited list of integers, where the jth integer of the ith element of paper represents the value of the jth cell of the ith row of the paper.|
You want to perform a sequence of folds on the paper, where you may fold anywhere along an axis that is in between two rows or columns of the paper. After performing a fold, we wish to model the folded paper as a new, flat piece of paper. We will do this by considering two overlapping cells as a single cell, with a value that is the sum of the individual cells.
You wish to perform a sequence of folds such that the value of some single cell in the resulting piece of paper is as large as possible. Return this value.
