Yes, it works! I'll try it tomorrow on a large array of data. 
Thank you very much!
This turns out to be a simple loop with a comparison of the 
existence of a key (whether it is included in an array or not) 
and a comparison of an existing array as a value with another 
array by this key. I wonder if can add this to lambda? In one 
line.
