ADAFIELD - Ada and Field


Ada the Ladybug owns a beautiful field where she grows vegetables. She often visits local Farmers Market, where she buys new seeds. Since two types of vegetable can't share same field, she always divide the field, by either vertical or horizontal line (she is very precise, so the width of line is negligible). Since she visits Farmers Market almost every day, she has already made a lot of such lines, so she needs your help with finding out the area of biggest field.

Input

The first line will contain 0 < T ≤ 200, the number of test-cases.

Then T test-cases follow, each beginning with three integers 1 ≤ N,M ≤ 2*109, 1 ≤ Q ≤ 105, top right corner of field (field goes from [0,0] to [N,M]) and number of field divisions.

Afterward Q lines follows:

0 x (0 ≤ x ≤ N), meaning that line was made vertically, on coordinate x

1 y (0 ≤ y ≤ M), meaning that line was made horizontally, on coordinate y

Sum of Q over all test-cases won't exceed 106

Output

Print Q lines, the area of biggest field after each line was made.

Example Input

A bit old, but can anyone help me spot the error in this algorithm?

A good problem.
I get Runtime Error at frist.
If you also get Runtime Error,try this:
1
1 1 4
1 0
0 1
1 1
0 0
The answer is:
1
1
1
1
This is because:if x=0 or y=0 or x=n or y=m,the line is on the border,and you don't need to do anything.But set or multiset will do something wrong!

Hint: Use the ordered map and ordered set. This way you can use binary search.

Got TLE at first. But after modifying the code, I'm getting WA despite the code giving right answers to given test cases. Any test cases I should particularly look after?

yeah. got AC in second chance. a good problem for beginners like us to learn lower bound and stl features.

It's really hard problem:3

Why am I getting Runtime Error now? I have implemented log N time per query

Take care of this test case:-
1
1 1 1
0 0
