In image processing, Laplacian filter is used as sharpening spatial filter. In a 2D array, the value of current position is calculated as

Question: You will be given a 2D array and then you will also be given k coordinates. Show the values of cells on the given k coordinates.
Hint: Do not change the value of the cell.

Input specification: First, you will be given two integers: the height (n) and width (m) of 2D matrix. The following n lines contain m integers which are between 0 and 255. On the next line, you will be given one integer (k). On the following k lines you will be given (x,y) coordinates of k cells where 1 ≤ (n,m, and k) ≤ 100.

Output specification: Show k integers.
