﻿/*  Problem 5. Maximal area sum
    Write a program that reads a text file containing a square matrix of numbers.
    Find an area of size 2 x 2 in the matrix, with a maximal sum of its elements.
        The first line in the input file contains the size of matrix N.
        Each of the next N lines contain N numbers separated by space.
        The output should be a single number in a separate text file.
    Example:
                input 	        output
                4
                2 3 3 4
                0 2 3 4         17
                3 7 1 2
                4 3 3 2
