Hi,

How can I turn and array like this this

[[1,2,3,4,5],[1,2,3,4,5]]

into this

[{:lt=\>1,:ln=\>1},{:lt=\>2,:ln=\>2},{:lt=\>3,:ln=\>3},{:lt=\>4,:ln=\>4},{:lt=\>5,:ln=\>5}]

Cheers

You can try something like that :

a = [[1,2,3,4,5],[1,2,3,4,5]]  
a.transpose.collect {|e| {:lt =\> e.first, :ln =\> e.last} }
