I am having trouble figuring out the elegant way to add an array of hashes
[{:a=>1,:b=>2,:c=>3},{:a=>1,:b=>2,:c=>3},{:a=>1,:b=>2,:c=>3}]
should return
[{:a=>3,:b=>6,:c=>9}]
I know it would probably involve mapping/reducing, but I can't figure out the right syntax, doesn't help that ruby-doc dot org doesn't match my version
I am using 1.8.7
