Problem Statement

翻译中…

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.

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.
