Problem Statement
Snuke has 1 gram of gold and 0 grams of silver now.
He will do trading of gold and silver for the following N days.
On each day, he has two choices: do nothing, or make a trade.
If he trades on Day $i (1 \leq i \leq N)$, the following will happen.
- If he has x grams of gold before the trade, exchange all of it for $x \times A_i$ grams of silver.
On the other hand, if he has x grams of silver, exchange all of it for x / A_i grams of gold.
Snuke's objective is to maximize the amount of gold he has in the end.
Find one way to achieve his objective.
Input
Input is given from Standard Input in the following format:
N
$A_1 A_2 \cdots A_N$
Output
Print the answer in the following format:
$v_1 v_2 \cdots v_N$
Here, v_i is an integer representing the action on Day $i (0 \leq v_i \leq 1). v_i=0$ means he does nothing, and v_i=1 means he makes a trade.
If there are multiple possible solutions, printing any of them will be considered correct.
Constraints
- $2 \leq N \leq 200000$
- $1 \leq A_i \leq 10^9$
- All values in input are integers.

The optimal sequence of actions is as follows.
-
Day 1: Do nothing.
-
Day 2: Exchange 1 gram of gold for 5 grams of silver.
-
Day 3: Exchange 5 grams of silver for 2.5 grams of gold.
