1334_D. Minimum Euler Cycle
You are given a complete directed graph K_n with n vertices: each pair of vertices u ≠ v in K_n have both directed edges (u, v) and (v, u); there are no self-loops. You should find such a cycle in K_n that visits every directed edge exactly once (allowing for revisiting vertices). We can write such cycle as a list of...

You are given a complete directed graph K_n with n vertices: each pair of vertices u ≠ v in K_n have both directed edges (u, v) and (v, u); there are no self-loops. You should find such a cycle in K_n that visits every directed edge exactly once (allowing for revisiting vertices). We can write such cycle as a list of...
