You have been hired at an open-air mine. You are to write a program to control a digger. For
your task, you have been given a `map' of all the underground resources in the mine. This map
comes as a file. The file has n rows. Each row has n space-separated integers. Each integer is
between zero and one hundred (inclusive). The file should be understood to represent a grid, n
wide by n deep. Each square in the grid can contain valuable resources. The value of these
resources can go from zero (no resources) to 100 (max resources).
The grid maps the resources just below the surface, and down to the lowest diggable depths.
The digger starts at the surface (so, just on top of the topmost row in the grid)—at any
horizontal position between 1 and n. The digger cannot dig directly downwards, but it can dig
diagonally in either direction, left-down, or right-down. In its first time-step, it will dig onto the
first row of the grid. In its second time-step, it'll hit the second row, and so on. When the digger
reaches row number n, it has to be air-lifted out of the mine, and is no longer usable.
Every time the digger hits a square with resources in it, we can reclaim those resources.
• Write a program that reads as a command-line argument a number n, this number is the
number of columns and rows mentioned above.
• It then reads from standard input n * n integers, each integer being between zero (0) and one
hundred (100), and then writes to standard out a single integer representing the maximum
possible profit
• An example of a proper running of your program would like this:

Here digger3_input is a file that I am providing separately on the Moodle (scroll down to sample
Inputs section), for your benefit, so you can use it to test and debug your program. I have also
made available a file called digger100, which is a 100x100 file (with the correct output included
as well). You are highly encouraged to use the Randomizer program you wrote during your work
on Worksheet 2 to create further input files.
