Suppose I have the following Array of tuples [ ['a',1], ['b',2], ['c','3' ] How can I convert this to a Hash? { 'a' => 1, 'b' => 2, 'c' => 3}?
Raw
array_to_hash.rb
a = [ ['a',1], ['b',2], ['c',3] ]
h={}
a.flatten!.each_with_index {|el, i| i % 2 == 0 ? h[el]=a[i+1] : () }
h
# => {"a"=>1, "b"=>2, "c"=>3}
