in reply to Read array of arrays in reverse order

Following script also does the job.Normally in Perl,array indexes starts from 0.
use strict; use warnings; my @my_arr = ( [1, 11, 0, 0], [12, 109, 0, 0], [16, 1, 16, 0], [14, 14, 2, 0], [45, 16, 5, 4], ); my $index=$#my_arr; while($index) { push @diagonal,$my_arr[$index][$index-1]; --$index; }
print join '-', @diagonal;
