Re: How to turn a tuple set into a 2D array ?

My question is opposite of what you had posted. 

How to convert

 a2 =  [[“London” “Paris”]          [“Paris” “Geneva”]          [“Brussels” “Paris”]]

to

s2 =  {<"London" "Paris"> <"Paris" "Geneva"> <"Brussels" "Paris">}

Thank you for your help.

Regards.
