Edward spent the whole weekend brainstorming problems involving 2-D arrays. Unfortunately, they were all too hard, so he came up with this instead:
You are given 
~N \times M~ integers, numbered from 
~1~ to ~N \times M~. You would like to arrange these numbers into an ~N \times M~ array 
~A~. The rows are numbered from ~1~ to 
~N~ and the columns from ~1~ to 
~M~. Denote the number assigned to the 
~i~-th cell from the top and the 
~j~-th cell from the left 
~A_{i, j}~. An arrangement is called valid if for all cells with 
~i > 1~, 
~A_{i, j} > A_{i-1, j}~, and for all cells with 
~j > 1~, 
~A_{i, j} > A_{i, j-1}~. You are also given 
~Q~ queries. For each query, a number 
~q_i~ is given, and you must return the number of different cells ~q_i~ can be placed in all valid arrangements.
Edward has no idea how to solve this problem either. Please help him solve it.
Input Specification
The first line will contain three integers ~N~, ~M~, and ~Q~, the dimensions of the array and the number of queries.
The next ~Q~ lines will each contain one integer ~q_i~, as specified in the problem statement.
Output Specification
Output ~Q~ lines, the ~i~-th line containing the number of different cells ~q_i~ can be placed in all valid arrangements.
Constraints
For all subtasks:
~1 \le N, M \le 5000~
~1 \le Q \le 10^6~
~1 \le q_i \le N \times M~
Subtask 1 [15%]
~1 \le N \times M \le 10~
~1 \le Q \le 10~
Subtask 2 [35%]
~1 \le N, M, Q \le 300~
Subtask 3 [50%]
No additional constraints.

Explanation for Sample 1
The two valid arrangements are:
~2~ and 
~3~ can be placed in two different cells, while ~1~ and 
~4~ can only be placed in one.

Explanation for Sample 2
The only valid arrangement is:
Since there is only 1 valid arrangement, each number can only be placed in 1 unique cell.
Sample Input 3
5 5 1
18
Sample Output 3
11
Explanation for Sample 3
The following diagram shows the 11 possible cells 
~18~ can be placed in. Green cells denote possible cells, while red cells denote otherwise:
Comments
I'm confused by sample 3 as how can 18 be placed in row 1 column 5? Wouldn't the cell right under it be 10 and since 18 is not less than 10 make the arrangement false?
i am certain that python is not being able to handle this, got all the answer correct but always TLE for part 3.
edit; it can, but only with pypy3 or pypy2
Are all queries distinct?
Not necessarily.
