Haoping has recorded a recitation for this week, and you can watch it below. If you cannot see the text, you can click on this link or click on the video to open the original video on YouTube.

For reference, please review the questions that he used in his Colab.

The questions in his Colab refer to the same dataset used in assignment 3. The last two questions are chanllenging, but hopefully it will make you farmiliar with map reduce. I am also going record a short video next week talking about the quesitons. Besides, you can drop by my OH if you have any questions.
