Array Merging into Hash

[Bucco]

Is there a simple way of merging two arrays into one has with one array
being the keys and the other being the values for the has?
a = [1, 2, 3']
b = ['a', 'b', 'c']
h = {1=>'a', 2=>'b', 3=>'c'}

Thanks

a=[1,2,3] => [1, 2, 3]
b=[:a,:b,:c] => [:a, :b, :c]
Hash[*a.zip(b).flatten]

=> {1=>:a, 2=>:b, 3=>:c}

p a.zip(b).inject({}){|h,(k,v)| h[k]=v;h}

Even more efficient:

require 'enumerator' => true
a = [1, 2, 3] => [1, 2, 3]
b = ['a', 'b', 'c'] => ["a", "b", "c"]
a.to_enumzip,b).inject({}) {|h,(k,v)| h[k]=v; h}

=> {1=>"a", 2=>"b", 3=>"c"}

Kind regards
