Hi all,
I have 4 letters (a,b,c,d) that can be combined in a string
I'm trying to create a function/sub that lists all the different combinations of the 4 letters such as:
1. a, b, c, d
2. aa, ab, ac, ad, ba, bb, bc, bd, ca, cb, cc, cd, da, db, dc, dd
3. aaa, aab, aac, abc, bac, ddd, ...
I worked on it a while and my head is going crazy. Any ideas?
