You are given an integer N. Your task is to construct the smallest possible positive integer that satisfies two conditions:

1) The sum of its digits is exactly N.

2) All of its digits are unique (digits from 1 to 9 can be used at most once).

If it's impossible to form such a number, you should return -1.

You are given a string “S”. Your task is to rearrange the characters of a string “S”, such that it does not contain any two adjacent characters which are the same.

If it is possible to rearrange the string “S”, then print any possible arrangement. else, print “not possible” without quotes.
