How to run an intermediate state

The repository was built while recording the lectures. Prior to each lecture, I tagged each commit so you can easily go back to an earlier state of the repo!

The tags are as follows:

• graphs-coloring
• graphs-find-paths
• graphs-intro
• graphs-make-undirected
• graphs-paths
• lists-append
• lists-big-3
• lists-duplicate
• lists-get-kth
• lists-insert-sort
• lists-length
• lists-merge-sort
• lists-prep
• lists-quick-sort
• lists-random-sample
• lists-remove-kth
• lists-reverse
• lists-rle
• lists-rotate
• misc-eval
• misc-n-queens
• misc-sierpinski
• numbers-approximate-pi
• numbers-decompose
• numbers-enhancing
• numbers-primes
• numbers-recurring-decimals
• start
• strings-anagram-checks
• strings-count-chars
• strings-generate-parentheses
• strings-justify
• strings-valid-parentheses
• trees-collect-nodes-at-level
• trees-intro
• trees-leaves
• trees-mirror
• trees-same-shape
• trees-size

When you watch a lecture, you can git checkout the appropriate tag and the repo will go back to the exact code I had when I started the lecture.
