{:val1=>"add", :val2=>"delete", :val3=>"update"} {:val1=>"add_name", :val2=>"delete_name", :val3=>"update_name"} {:val1=>"add_city", :val2=>"delete_city", :val3=>"city"}

i want convert ret_val array values assigned val1, val2, , val3 can extracted giving val1, val2, , val3.so see key , value pair of comma separated pairs . expected output :

val1 : add val2 : delete val3:update

till last row returned api. please suggest. note: api return response in above format duplicate key.
