No, I meant
how does every line like 1 2 3 4
relate to the file1 ?
We take only 1 2 3 4 columns from file1?
A B C D? what is the logic we're trying to achieve at the end?
To summarize the column's pluses and zeroes in different arrays?
Maybe it is an XY problem we're facing here.
At this point I got this:
we take the first line 1 2 3 4, decrement every element,
then in a loop we push 4 elements into different four arrays according to these values.
At the end we're getting four arrays that look like this:
A0+000+0A0+000+0A0+000+0A0+000+0A0+000+0.
So what's the end goal?
