Say I've got two 1-dimensional lists
A = {1,2,3}
B = {a,b,c}
How do I
- create a list of all pairs from list
A
such that the result looks like{{1,2},{1,3},{2,3}}
? - create a list of all pairs from lists
A
andB
such that the result looks like{{1,a},{1,b},{1,c},{2,a},{2,b},{2,c},{3,a},{3,b},{3,c}}
?
I would also need both options, one with no duplicates as above and one with duplicates, e.g. one where the result from case 1 also includes {{2,1},{3,1},{3,2}}
.
