Filter an array of hashes Ruby -

i have array of hashes:

[    [0] {     "10:45" => 40,     "11:00" => 40,     "11:15" => 40,     "11:30" => 40     "13:30" = >35,     "14:00" => 40,     "15:00" => 40      },    [1] {     "12:00" => 38,     "12:45" => 39,     "13:00" => 39,     "13:15" => 39,     "13:30" => 39     } ] 

i need new filtered array:

 [    [0] {     "10:45" => 40,     "13:30" = >35,     "14:00" => 40      },    [1] {     "12:00" => 38,     "12:45" => 39     } ] 

in other words "delete key/value if value equals right before value".

let's try this, have array

array = [    {     "10:45" => 40,     "11:00" => 40,     "11:15" => 40,     "11:30" => 40,     "13:30" = >35,     "14:00" => 40,     "15:00" => 40    },    {     "12:00" => 38,     "12:45" => 39,     "13:00" => 39,     "13:15" => 39,     "13:30" => 39    } ] 

let's remove duplicate values

def get_results(array)   final_array = []    array.each |hash|     final_hash = {}      hash.each |key, value|       final_hash[key] = value unless final_hash.values.last == value     end     final_array << final_hash   end   final_array end 

hope helps!
