I have a nested hash:

Hash = { "abc" => { "def" => { "count" => 120 } } ,
          "ABC" => {"DEF" => { "COUNT" => 100 } },
          "sample" => {"samplecode" => {"COUNT" => 3 } } }

I want to convert the entire hash into lowercase. If any duplicates exist, I want to add the count value. The resulting hash should be:

Result = { "abc" => { "def" => { "count" => 220 } } ,
            "sample" => { "samplecode" => { "count" => 3} } }

    This question's poster gets lambasted and downvoted, whilst another [poster](https://stackoverflow.com/q/49665891/5101493) (moments earlier) has a few answers to his seemingly ill-researched question without any criticism or any downvoting. – Sagar Pandya Apr 05 '18 at 07:44

This would provide solution for your case: Next time it would be great if you could explain what method did you try and where did you face the issue in ..

result = {}
hash.each{|k,v|
  result[k.downcase] = result[k.downcase].present? ? result[k.downcase] : {}
  v.each{|key,values|
    result[k.downcase][key.downcase]= result[k.downcase][key.downcase].present? ? result[k.downcase][key.downcase] : {}
    values.each{|count, variable|
      result[k.downcase][key.downcase][count.downcase] = result[k.downcase][key.downcase][count.downcase].to_i + variable.to_i
    }
  }
}
