Helo, How to convert an array to a hash? for example, > x => ["a", "hello", "b", "world", "c", "welcome", "d", "baby"] to: > z => {"a"=>"hello", "b"=>"world", "c"=>"welcome", "d"=>"baby"} And, for creating an array quickly, I could say: x = %w/a hello b world c welcome d baby/ but how to creat a hash like this way? Thanks.
