Coordinates of a Point

Source: beecrowd

Version: Phuoc Hung OJ Extended

Problem Statement

Given real coordinates $(x,y)$, identify the origin, a coordinate axis, or one of the four quadrants according to the signs of the coordinates.

Input

One line contains real coordinates $x,y$, each with up to two fractional digits.

Output

Print Origem at $(0,0)$, Eixo X on the non-origin horizontal axis, Eixo Y on the non-origin vertical axis, or Q1/Q2/Q3/Q4 for the respective quadrants.

Subtasks

• Subtask 1 (20 points): $-10\le x,y\le 10$; at most two decimal places. $x\ne0,y\ne0$.
• Subtask 2 (30 points): $-100\le x,y\le 100$; at most two decimal places.
• Subtask 3 (50 points): $-1000\le x,y\le 1000$; at most two decimal places.

Examples

Example 1

Input

0.00 0.00

Output

Origem

Explanation

The input gives 0.00, 0.00. The point (0.00, 0.00) is checked for the origin, the axes, and then the signs of both coordinates. Therefore the required output is ['Origem'].

Example 2

Input

-3.00 4.00

Output

Q2

Explanation

The input gives -3.00, 4.00. The point (-3.00, 4.00) is checked for the origin, the axes, and then the signs of both coordinates. Therefore the required output is ['Q2'].

Example 3

Input

0.00 -5.00

Output

Eixo Y

Explanation

The input gives 0.00, -5.00. The point (0.00, -5.00) is checked for the origin, the axes, and then the signs of both coordinates. Therefore the required output is ['Eixo Y'].
