Description

Fabrics often have repeating patterns on them, such as a tessellation of
carrots and bats.


A given image, such as a carrot in the above example, takes up a certain
number of square inches on the fabric. In addition, a piece of fabric
with more than one image will have those images in some sort of simple
integral ratio, such as 3 carrots for every 2 bats. One instance of
images in the given ratio is considered a full set.


Fabrics are sold by the square yard (and, for those of you who have
forgotten, there are 36 inches to the yard). Given a collection of
images, their sizes, and the ratios in which they occur, what is the
maximum number of full sets that could possibly appear on one, two, and
three square yards of patterned fabric?


(Note that this maximum implies totally arbitrary shapes and placements
for the images, which may be different for the three lengths of fabric;
the particulars of the layout are irrelevant for the purposes of the
problem.)

Input Format

Input to this problem will begin with a line containing a single integer
N (1 ≤ N ≤ 100) indicating the number of data sets.
Each data set consists of the following components:


  • A line containing a single integer I (1 ≤ I ≤ 10)
    indicating the number of images in a particular pattern;

  • A series of I lines, each with two integers S,

    R (1 ≤ S ≤ 1000; 1 ≤ R ≤ 100) separated
    by spaces representing the images. S is the number of square inches
    that the image occupies; R is the count of the images contained in
    a full set.

Output Format

For each data set, print "A B C", where
A is the maximum number of full sets that could possibly appear on
one square yard of fabric, B is the maximum number of full sets that
could possibly appear on two square yards of fabric, and C is the
maximum number of full sets that could possibly appear on three square yards
of fabric.
