Given a 2D rectangular matrix of boolean values, write a function which returns whether or not the matrix is the same when rotated 180 degrees. Additionally verify that every boolean true is accessible from every other boolean true if a traversal can be made to an adjacent cell in the matrix, excluding diagonal cells. That is , (x , y ) can access the set [ ( x + 1 , y ) , ( x - 1 , y ) , (x , y - 1 ) , (x , y + 1 ) ] For example, the matrix { { true , false } , { false , true } } should not pass this test.
