The 12p Grind
On 22nd January 26, I discovered has solved every 17 point problem. This motivated me to start one of these on my own. However, I am not as good of a coder, so I'll be doing 12 pointers instead 😂
2026-01-22 - Starting 12p grind (24/454)
2026-02-23 - One page completed (50/454)
Small Wins
First user to solve GCJ16R1AB, Bob & Binary Strings in Python
First user to solve Waterloo '08 Spring E - Balance, apparently (I don't know why 's solutions are not counted...) - Check to see the formula which I used to solve it.
Solving Under the Rug. I genuinely can not express to you how much I dislike Subcase 6 of Test Case 3.
