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:
, , , , , , , , , ,
, , , ???????
???, , , , ??,
?, , , , , , ???
, , , , , ????,
???, , , , , , ,
???????, , ,
???, , , , , ??
, , , , , , , , , ,
, , , , , ????,
