Hi Monks. Is there any way I can use grep to parse through a 2D array and extract rows for which particular elements are greater than a specific value. Consider the following example:
use strict; use warnings; use Data::Dumper; my @arr; @arr = ( [ 'A', 1, 0, 5, 6, 2 ], [ 'B', 3 , 4 , 5 , 6 , 7 ], [ 'C' , 2 , 4 ,3 ,5 ], [ 'D' , 6 , 7 , 8 ,8 ], [ 'E' , 2 , 5 , 4 , 5 ], [ 'F' , 4 , 3 , 2 ,2 ], [ 'G' , 1 , 2 , 4, 5 ], [ 'H' , 1 , 4 , 5, 6 ] ); my @rows = grep { grep {$_ > 6} @$_ } @arr; print Dumper(\@rows);
The above code checks the each 'row' of the 2D array and extracts those arrays(1D)/entries if any of the column entries is greater than the threshold( in this case, 6). I would like to able to set multiple checks across multiple columns,i.e. for eg: extract rows for which the second column entry > 4 and 4th column entry > 3 and so on.

Any idea how to do this ? Thanks in advance
