This article is about generating Power set in lexicographical order.
Input : abc Output : a ab abc ac b bc c
The idea is to sort array first. After sorting, one by one fix characters and recursively generates all subsets starting from them. After every recursive call, we remove last character so that next permutation can be generated.
a ab abc ac b bc c
