Find out string that would come in first in dictionary among strings generated by combination of given strings

Given a list of strings of different length, we need find out string that would come in first in dictionary among strings generated by combination of given strings.

For Input: cda,bcs,fgr,cd

Is there any better way than generating all the combinations of strings and comparing them? Please help.
