In Ruby, create a hash of a hash map with the total occurrences of key values to output in a JSON style as shown.

require 'json'

require $\text{'}$csv$\text{'}$

def my$\_$data$\_$process$($str$)$

arr $=$ str$.$split$("\backslash ",\backslash "")$

index $=0$

values $=[]$

while $($index $<$ arr.length$)$

values$[$index$]=$ arr$[$index$].$split$(",")$;

index $+=1$

end

# count occurrances of Gender: $\{$Male$,$ Female$\},$ Email, Age, City, Device, Order At

# create map with totals

arr$\_$map $=\{\}$

arr$\_$map$[$:Gender$]=\{$ :Male $=>0,$ :Female $=>5\}$

arr$\_$map$[$:Email$]=\{$ :domain$1=>0,$ :domain$2=>5\}$

arr$\_$map$[$:Age$]=\{$ :a $=>0,$ :b $=>5,$ :c $=>1\}$

arr$\_$map$[$:City$]=\{$ :Male $=>0,$ :Female $=>5\}$

arr$\_$map$[$:Device$]=\{$ :Male $=>0,$ :Female $=>5\}$

arr$\_$map$[$:"Order At$"]=\{$ :Male $=>0,$ :Female $=>5\}$

json $=$ JSON.pretty$\_$generate$($arr$\_$map$)$

s $=$ json.gsub $/[$

$]/,\text{'}\text{'}$

s$.$delete! $\text{'}\backslash \backslash \text{'}$

s

end
