How can I sum arrays element-wise in Perl?

Question

I have two arrays:

@arr1 = ( 1, 0, 0, 0, 1 );
@arr2 = ( 1, 1, 0, 1, 1 );

I want to sum items of both arrays to get new one like

<         


        

Answer 1

what's wrong with looping over arrays? that's the fundamentals.

@arr1 = ( 1, 0, 0, 0, 1 );
@arr2 = ( 1, 1, 0, 1, 1 );
for ($i=0;$i
