Problem Statement

Soil Level Difference Problem Description Read the input from STDIN and print the output to STDOUT. Do not print arbitrary strings anywhere in the program, as these interfere with the standard output and test cases will fail. A landscaper is laying out a square plot for a client's new home. The plan calls for the house itself to sit as a smaller square positioned exactly in the middle of the plot, with a fence running along every edge of that inner square so the remaining outer strip can be split evenly into garden beds. Once building began, the crew found the ground was not level and soil would have to be moved between sections to flatten it. The whole plot was recorded as a matrix giving the soil height of every cell outside the fence line itself. Write a program that reports how much soil needs to move by computing the absolute difference between the total soil level of the inner square and the total soil level of the outer ring.
