To find corner blocks among instantiated blocks

Hello, I want to find the corner blocks among the instantiated blocks in the scene. I want blocks to surround the main path blocks and colorize corner blocks.

This is test code :

     public GameObject box;
     GameObject[] gameObjects;
 
     private void Awake()
     {
         gameObjects = GameObject.FindGameObjectsWithTag("Floor");
 
         GetPos();
     }
 
     void GetPos()
     {
         for (int a = 0; a < gameObjects.Length; a++)
         {
             for (int i = -1; i < 2; i++)
             {
                 for (int j = -1; j < 2; j++)
                 {
                     Collider[] col = Physics.OverlapSphere(gameObjects[a].transform.position + new Vector3(i, 0, j), 0.25f);
                     if (col.Length <= 0)
                         GenerateBlocks(i, j, a);
                 }
             }
         }
     }
 
     void GenerateBlocks(int x, int z, int y)
     {
         GameObject go = Instantiate(box, gameObjects[y].transform.position + new Vector3(x, 0, z), Quaternion.identity);

 go.GetComponent<Renderer>().material.color = Color.red;
 go.transform.parent = transform;
     }

The result: (with 2 path blocks) alt text
