Hi All
I'm looking some better solution for the below list manipulation:
l1={a,b,c};
l2={{1,2,3},{4,5,6},{7,8,9}};
output = {{a,1},{a,2},{a,3},{b,4},{b,5},{b,6},{c,7},{c,8},{c,9}}
It's a simple distributions of terms.
I used this solution, but I think it's not an elegant one:
f[a_, b_] := Flatten[{a, #}] & /@ b;
MapThread[f, {l1, l2}] // Flatten[#, 1] &
Some clue?
Maybe with Outer or Inner?
Thanks in advance!
Murta
