Start a new notebook on your virtual machine, then complete the following three parts of the lab:
- review files and JSON -- this should help a lot with P1 if you're rusty with those concepts
- visualize orders of growth -- get an intuition for what N and C mean
- learn merge sort -- this is an important algorithm for sorting lists that has complexity between O(N) and O(N**2)
Have fun, and let us know if you have any questions!
