Write a code in java to recursively count how many "?" marks are grouped.

A group is when "?" is touching left, right, up, and down. NOT diagonally. A comma is used to represent a blank space in the matrix.

The first parameter will be a string containing all of the values in the grid. The values in the string must be converted into a String[][] matrix. The second parameter will contain a String that contains all of the coordinate pairs to check.

Print out the number of ? marks are grouped at each of the coordinate pairs.

Example:

, , , , , , , , , ,

, , , ???????

???, , , , ??,

?, , , , , , ???

, , , , , ????,

???, , , , , , ,

???????, , ,

???, , , , , ??

, , , , , , , , , ,

, , , , , ????,

1 1 2 7 2 0 6 6

output:

0

16

4

13

int start(int a, int b) {
