Crunch character combination and discard similar content
Hi guys !
I generated the power set of the set S={a,b,c} using crunch:
Code:
crunch 1 3 abc
and get the 39 possible subsets:
Code:
a
b
c
aa
abacba
bb
bccacb
cc
…
As the order of the character in the string is not important, I am trying to get rid of the subsets containing the same characters and keep only one (see before: green, the one to keep; red the ones to discard).
In order to obtain:
Code:
a
b
c
aa
ab
ac
bb
bc
cc
...
Any language is fine.
If someone could put me on the track !
