1. Writing my own code definitely helped me understand the problem better. It was kind of lucky that the most common character in each of the secret texts was in fact " ". It made me understand the work that the cipher is doing better. 2. I watched like 3 different youtube videos about the Kasiski examination process after reading the wiki page. I quickly used "the" to get a difference to the next "the" that mapped the same as 42, so I knew the keyword had to be a multiple of 2,3, or 7. I tried the process with 3 and got nowhere, so I tried it with 6 on a whim. I got the first two letters of the code to be PY, then I couldn't figure out the third so I skipped it, and got the 4th letter to be H, so I made the guess that the keyword was PYTHON and I was right!
