Lesson 3: functions init_batch, merge_batches, filter_batch used to implemented continuous batching

Could someone let me know where to find the scripts of the following three functions: init_batch, merge_batches, and filter_batch? These three functions are used in implementing continuous batching in Lesson 3. I could not find them in the Jupyter Notebooks of Lesson 1 or Lesson 2.
