3466.Looking for Owls

Time Limit: 1s Memory Limit: 256MB

Emperor Palpatine loves owls very much. The emperor has some blueprints with the new Death Star, the blueprints contain n distinct segments and m distinct circles. We will consider the segments indexed from 1 to n in some way and the circles - indexed from 1 to m in some way.

Palpatine defines an owl as a set of a pair of distinct circles (i,j) (i \lt j) and one segment k, such that:
circles i and j are symmetrical relatively to the straight line containing segment k; circles i and j don't have any common points; circles i and j have the same radius; segment k intersects the segment that connects the centers of circles i and j.
Help Palpatine, count the number of distinct owls on the picture.

Input Format(From the terminal/stdin)

The first line contains two integers - n and m (1 \le n \le 3 \cdot 105, 2 \le m \le 1500).

The next n lines contain four integers each, x1, y1, x2, y2 - the coordinates of the two endpoints of the segment. It's guaranteed that each segment has positive length.

The next m lines contain three integers each, xi, yi, ri - the coordinates of the center and the radius of the i-th circle. All coordinates are integers of at most 104 in their absolute value. The radius is a positive integer of at most 104.

It is guaranteed that all segments and all circles are dictinct.

Output Format(To the terminal/stdout)

Print a single number - the answer to the problem.

Please, do not use the %lld specifier to output 64-bit integers is C++. It is preferred to use the cout stream or the %I64d specifier.

Hints

Here's an owl from the first sample. The owl is sitting and waiting for you to count it.
