Question

Ruby code is：

    a = []
    h = {}
    2.times.each do |i|
      %w(a b c).each do |x|
        h[x] = x + i.to_s
      end
      a << h
    end

the result is:

a = [{"c"=>"c1", "b"=>"b1", "a"=>"a1"}, {"c"=>"c1", "b"=>"b1", "a"=>"a1"}]

but i hope the result is:

a = [{"c"=>"c0", "b"=>"b0", "a"=>"a0"}, {"c"=>"c1", "b"=>"b1", "a"=>"a1"}]

who can help me.thx

Answer 1

After a << h you have to do h = {}. This is because you are assigning a new object to h so that it doesn’t override the previous values.
