standard outputInna loves sweets very much. That's why she wants to play the "Sweet Matrix" game with Dima and Sereja. But Sereja is a large person, so the game proved small for him. Sereja suggested playing the "Large Sweet Matrix" game.

The "Large Sweet Matrix" playing field is an *n* × *m* matrix. Let's number the rows of the matrix from 1 to *n*, and the columns — from 1 to *m*. Let's denote the cell in the *i*-th row and *j*-th column as (*i*, *j*). Each cell of the matrix can contain multiple candies, initially all cells are empty. The game goes in *w* moves, during each move one of the two following events occurs:

- Sereja chooses five integers
*x*_{1},*y*_{1},*x*_{2},*y*_{2},*v*(*x*_{1}≤*x*_{2},*y*_{1}≤*y*_{2}) and adds*v*candies to each matrix cell (*i*,*j*) (*x*_{1}≤*i*≤*x*_{2};*y*_{1}≤*j*≤*y*_{2}). - Sereja chooses four integers
*x*_{1},*y*_{1},*x*_{2},*y*_{2}(*x*_{1}≤*x*_{2},*y*_{1}≤*y*_{2}). Then he asks Dima to calculate the total number of candies in cells (*i*,*j*) (*x*_{1}≤*i*≤*x*_{2};*y*_{1}≤*j*≤*y*_{2}) and he asks Inna to calculate the total number of candies in the cells of matrix (*p*,*q*), which meet the following logical criteria: (*p*<*x*_{1}OR*p*>*x*_{2}) AND (*q*<*y*_{1}OR*q*>*y*_{2}). Finally, Sereja asks to write down the difference between the number Dima has calculated and the number Inna has calculated (D - I).

Unfortunately, Sereja's matrix is really huge. That's why Inna and Dima aren't coping with the calculating. Help them!

Input

The first line of the input contains three integers *n*, *m* and *w* (3 ≤ *n*, *m* ≤ 4·10^{6}; 1 ≤ *w* ≤ 10^{5}).

The next *w* lines describe the moves that were made in the game.

- A line that describes an event of the first type contains 6 integers: 0,
*x*_{1},*y*_{1},*x*_{2},*y*_{2}and*v*(1 ≤*x*_{1}≤*x*_{2}≤*n*; 1 ≤*y*_{1}≤*y*_{2}≤*m*; 1 ≤*v*≤ 10^{9}). - A line that describes an event of the second type contains 5 integers: 1,
*x*_{1},*y*_{1},*x*_{2},*y*_{2}(2 ≤*x*_{1}≤*x*_{2}≤*n*- 1; 2 ≤*y*_{1}≤*y*_{2}≤*m*- 1).

It is guaranteed that the second type move occurs at least once. It is guaranteed that a single operation will not add more than 10^{9} candies.

Be careful, the constraints are very large, so please use optimal data structures. Max-tests will be in pretests.

Output

For each second type move print a single integer on a single line — the difference between Dima and Inna's numbers.

Note

Note to the sample. After the first query the matrix looks as:

22200

22200

00000

00000

After the second one it is:

22200

25500

03300

00000

After the third one it is:

22201

25501

03301

00001

For the fourth query, Dima's sum equals 5 + 0 + 3 + 0 = 8 and Inna's sum equals 4 + 1 + 0 + 1 = 6. The answer to the query equals 8 - 6 = 2. For the fifth query, Dima's sum equals 0 and Inna's sum equals 18 + 2 + 0 + 1 = 21. The answer to the query is 0 - 21 = -21.
