Convert 2 arrays to 1 hash

Question

array1 = [1,2,3,4]

array2 = [true,false,true,false]

expected output : [:1 => true, :2 => false, :3 => true, :4 => false]

Would like to make the array1 values as keys of the hash and array2 values as the hash values.

Using ruby 1.8

Can someone please help how to achieve this.

@Severin: array1 here is just an example but in my case its a string and can be anything. — Ross, Mar 25 '14 at 07:51

Try:

output = Hash[array1.zip(array2)]

Perfect, works fine with the example i provided in my question. But doesn't work if the values are same in array1 = [1,1,1,1] returns {1=>false} – Ross Mar 25 '14 at 08:06
@Ross Hash key should be unique, what is the expected result when array1 is `[1,1,1,1]` ? – xdazz Mar 25 '14 at 08:11
