Question

Marty wants to protect Alex, and for that, he has arranged a special force of expert officers. But Captain Chantel is also an intelligent enemy of Marty, and she has also arranged a bunch of expert shooters.

 
Every man has some experience points. In this scenario, Marty's men have "even" experience points, and Captain Chantel's men have "odd" experience points.

Now, Marty's strategy is to place his men in ascending order so that, if an enemy is going to attack, then the more experienced men can easily take over the enemy.

But, Captain Chantel also has a strategy. Captain Chantel will send her force in descending order of experience points so that their motive of killing Alex will be achieved, as, even if the most experienced ones die the less experienced ones can reach inside and kill Alex.

Now, you have been given an array of experience points of men, and you have to find the men belonging to Marty's Force and Captain Chantel's Force and print their experience points in appropriate order.

Input

Output
