 Description
 You’re giving a party in the garden of your villa by the sea. The party is a huge success, and everyone is
here. It’s a warm, sunny evening, and a soothing wind sends fresh, salty air from the sea. The evening is
progressing just as you had imagined. It could be the perfect end of a beautiful day.
But nothing ever is perfect. One of your guests works in weather forecasting. He suddenly yells, “I
know that breeze! It means its going to rain heavily in just a few minutes!” Your guests all wear their best
dresses and really would not like to get wet, hence they stand terrified when hearing the bad news.
You have prepared a few umbrellas which can protect a few of your guests. The umbrellas are small, and
since your guests are all slightly snobbish, no guest will share an umbrella with other guests. The umbrellas
are spread across your (gigantic) garden, just like your guests. To complicate matters even more, some of
your guests can’t run as fast as the others.
Can you help your guests so that as many as possible find an umbrella before it starts to pour?
Given the positions and speeds of all your guests, the positions of the umbrellas, and the time until it starts
to rain, find out how many of your guests can at most reach an umbrella. Two guests do not want to share
an umbrella, however.  Input
 The input starts with a line containing a single integer, the number of test cases.
Each test case starts with a line containing the time t in minutes until it will start to rain (1 ≤ t ≤ 5).
The next line contains the number of guests m (1 ≤ m ≤ 3000), followed by m lines containing x and
ycoordinates as well as the speed si in units per minute (1 ≤ si ≤ 3000) of the guest as integers, separated
by spaces. After the guests, a single line contains n (1 ≤ n ≤ 3000), the number of umbrellas, followed by
n lines containing the integer coordinates of each umbrella, separated by a space.
The absolute value of all coordinates is less than 10000.  Output
 For each test case, write a line containing “Scenario #i:”, where i is the number of the test case
starting at 1. Then, write a single line that contains the number of guests that can at most reach an umbrella
before it starts to rain. Terminate every test case with a blank line.  sample input
