input: Write a function in Python to determine how many integer coordinates are enclosed within a given square.
  
  assert count_Integer_Coordinates(1,1,4,4) == 4
  assert count_Integer_Coordinates(1,2,1,2) == 1
  assert count_Integer_Coordinates(4,2,6,4) == 1
output: def count_Integer_Coordinates(x1, y1, x2, y2):

      right = max(x1, x2)
      bottom = min(y1, y2)
      top = max(y1, y2)
      count = 0
      for x in range(left + 1, right):
          for y in range(bottom + 1, top):
              count += 1
      return count
