ping CTF 2023

Overall Placement: #63/517

Thoughts:

This was a fun CTF! I was admittedly a little frustrated with my performance because I failed to solve some very easy problems (ancient-genius D:) but overall I had a good time with a lot of the challenges! I’m also quite proud that I managed to solve my first LLL problem, even though it was a relatively easy one.
