Looks like "Rotate Image" is the only Matrix problem that remains. It was nice to learn more about "Backtracking" -- a term I often encounter -- while attempting to solve "Word Search". From my current understanding, it is like Brute Force but with short-circuiting. It also seems quite similar to Depth First Search, and I'm currently unaware of how DFS and Backtracking differ. I'm hoping to learn more though.
