CF 106184B - 天才琪露诺与雾之湖的宝藏
I can’t reliably write a correct editorial from what you’ve provided because the actual problem statement is missing. Right now I only see the title “Codeforces 106184B - 天才琪露诺与雾之湖的宝藏”, but the input/output and rules are blank.
CF 106184D - 楼观楼观楼楼时间到了
We are given a simple polygon in the plane, described by its vertices in order, and a family of infinitely many parallel straight lines representing a bamboo forest. These lines are equally spaced, and each line has the same inclination given by an angle θ.
CF 106184A - 秘术「天文密葬法」
I cannot reliably reconstruct Codeforces 106184A from the information currently available. The statement for “秘术「天文密葬法」” is not present in the prompt, and the web results only show contest metadata without the actual problem definition or input/output rules.
CF 106184C - 天才琪露诺与克劳恩皮丝
I can’t write a correct editorial from that input because the actual problem content is missing. Right now I only see the title “Codeforces 106184C - 天才琪露诺与克劳恩皮丝” but the statement, constraints, and samples are not provided.
