Quadrants and axes

There are $n$ points on the two dimensional plane. Given the coordinates $(x, y)$ of each point, count how many points lie in each of the four quadrants and how many lie on an axis.

The quadrant of a point follows the signs of its two coordinates. $x > 0$ and $y > 0$ is the first quadrant, $x < 0$ and $y > 0$ is the second quadrant, $x < 0$ and $y < 0$ is the third quadrant, and $x > 0$ and $y < 0$ is the fourth quadrant.

A point whose $x$ or $y$ is $0$ belongs to no quadrant and counts as a point on an axis. The origin is a point on an axis as well.

The first line contains the number of points $n$. ($1 \le n \le 1000$)

Each of the next $n$ lines contains the coordinates $x_i$ and $y_i$ of one point, separated by a space. ($-10^6 \le x_i, y_i \le 10^6$)

The same coordinates may be given more than once, and every occurrence is counted separately.

Print five lines in this format.

Q1: <number of points in the first quadrant>
Q2: <number of points in the second quadrant>
Q3: <number of points in the third quadrant>
Q4: <number of points in the fourth quadrant>
AXIS: <number of points on an axis>

Write the labels in upper case, and put one space after the colon before the count.
