Given  a grid of n*m consisting of O's and X's. The task is to find the number of 'X' total shapes.
Note: 'X' shape consists of one or more adjacent X's (diagonals not included).

Example 1:

Input: grid = {{X,O,X},{O,X,O},{X,X,X}}
Output: 3
Explanation:
The grid is-
X O X
O X O
X X X
So, X with same colour are adjacent to each
other vertically for horizontally (diagonals
not included). So, there are 3 different groups
in the given grid.



Example 2:

Input: grid = {{X,X},{X,X}}
Output: 1
Expanation:
The grid is-
X X
X X
So, X with same colour are adjacent to each
other vertically for horizontally (diagonals
not included). So, there is only 1 group
in the given grid.


You don't need to read or print anything. Your task is to complete the function xShape() which takes grid as input parameter and returns the count of total X shapes.
