I have to read an input file structured like this:
3
1 3 49 2
0 4 2 12
0 7 5 2
where three is the number of test cases so the number of the arrays and the three lines represents
the arrays. I have to store each line in a different array to apply a method to test them, so I was wondering using a LinkedList
of arrays or something like that, the problem is that i don't know how to
properly read the lines and how store them.
