Dear Monks
I am trying to solve a permutation probelm and looking for pointers. The different permutation we can create by putting pair of paranthesis before,after or in between given number.
Example: for p=2 and n= 123, we may have: 
(1) (2) 3
(1) 2 (3)
(1 2) (3)
(1 (2 3))
((1 2 3))
1 ((2 3))
etc..
Thanks,
artist
