Problem Statement
For a sequence of non-negative integers , let us define its as the integer such that, for all non-negative integer :
- the s place of is if and only if there is an odd number of elements among whose s place is .
You are given a sequence of non-negative integers of length .
Let $\lbrace s _ 1,s _ 2,\ldots,s _ k\rbrace\ (s _ 1\lt s _ 2\lt\cdots\lt s _ k)$ be the set of all non-negative integers that can be the of a not-necessarily-contiguous (possibly empty) subsequence of .
Given integers and , print in this order.
Constraints
- All values in the input are integers.
Input
The input is given from Standard Input in the following format:
Output
Print in ascending order of , separated by spaces.
4 1 8
2 21 17 21
0 2 4 6 17 19 21 23
There are not-necessarily-contiguous subsequences of : $(),(2),(17),(21),(2,17),(2,21),(17,21),(21,17),(21,21),(2,17,21),(2,21,17),(2,21,21),(21,17,21)$, and , whose s are as follows.
- The of is .

- The of is .
Therefore, the set of all non-negative integers that can be the of a subsequence of is .
