a.sort_by{|i| i[1]}

Array#sort_by calls the block for each element of the array, and uses the
return value as a key to use in sorting.

I hope this helps

[["raja",1],["Arun",5],["babu",3]].sort {|a,b| a[1] <=> b[1] };

Hi Stefano,

a.sort_by{|i| i[1]}

Array#sort_by calls the block for each element of the array, and uses
