How to create multi-dimensional array in perl?

You get a one-dimensional array because the array a1 is expanded inside the parens. So, assuming.

I would propose to work through perlreftut, perldsc and perllol, preferably in the same day and preferably using Data::Dumper to print data structures.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
