Problem Descriptionclarke is a patient with multiple personality disorder. One day, Clarke turned to a game player of Minecraft.
On this day, Clarke sets up the local network and chose create mode for sharing he achievements with others. Unfortunately, a naughty kid came his game. He placed a few creepers in Clarke ' s castle! When Clarke returned he castle without create mode, Creepers suddenly blew (what a amazing scene!). Then Clarke's castle in ruins, the materials scattered over the ground.
Clark had no choice but to pick up these ruins, ready to rebuild. After Clarke built some chests (boxes), He had to pick up the material and stored them in the chests. Clarke clearly remembered the type and number of each item (each item is made of only one type material). Now Clarke want to know how many times he has to transport at least.
Note:materials which have same type can be stacked, a grid can store up to materials of same type at the most. Different types of materials can be transported together. Clarke ' s bag has 4*9=36 grids.

Inputthe First line contains a numberT(1≤t≤) , the number of test cases.
For each test case:
The first line contains a numberN, the number of items.
ThenNLines follow, each line contains the integera,b(1≤a,b≤) , a denotes the type of material of this item, and b denotes the number of this material.

Outputfor each testcase, print a number, and the number of times that Clarke need to transport at least.

Sample Input232 333 332 33105 4676 3787 3098 4995 3203 4802 4448 3915 333100 499

Sample Output12 Hint:the First sample, we need to use 2 grids to store the materials of type 2 and 1 grids to store the mat Erials of Type 3. So we only need to transport once;

Sourcebestcoder Round #56 (Div.2) topic: Want to carry some items with the box, each item has material and quantity. , a box has 36 compartments, each of which can only be loaded with one material, and a lattice can only fit up to 64 items. The final output is the need to be transported several times. See the code.
