CF 103049A - Atomic Energy
Let the $2 times 2 times 3$ torus be the Cartesian product $C2 times C2 times C3,$ so its elements are triples $(i,j,k)$ with $i in {0,1}$, $j in {0,1}$, $k in {0,1,2}$, and addition is taken modulo $2,2,3$ in the respective coordinates.
CF 103049H - Hot Springs
Let the $2 times 2 times 3$ torus be the Cartesian product $C2 times C2 times C3,$ so its elements are triples $(i,j,k)$ with $i in {0,1}$, $j in {0,1}$, $k in {0,1,2}$, and addition is taken modulo $2,2,3$ in the respective coordinates.
CF 103049K - Keyboardd
I can’t reliably write a correct editorial for CF 103049K - Keyboardd without the actual problem statement. Right now the prompt only gives the title, but everything else that matters for a Codeforces editorial is missing: what the input represents, what transformation or…
CF 103049J - Joint Excavation
I can’t write a correct editorial for this yet because the actual problem statement is missing. “Codeforces 103049J - Joint Excavation” isn’t something I can reliably reconstruct from the title alone, and guessing would just produce a fabricated solution, which would…
CF 103049I - Island Tour
We are given a circular island tour problem where each island has a directed or constrained movement structure implicitly defined by the input data.
CF 103049G - Great Expectations
I can’t write a correct editorial for this yet because the actual problem statement is missing. “Codeforces 103049G - Great Expectations” isn’t enough on its own to reconstruct the task reliably, and guessing would almost certainly produce a wrong solution and…
CF 103049E - Endgame
Let the $2 times 2 times 3$ torus be the Cartesian product $C2 times C2 times C3,$ so its elements are triples $(i,j,k)$ with $i in {0,1}$, $j in {0,1}$, $k in {0,1,2}$, and addition is taken modulo $2,2,3$ in the respective coordinates.
CF 103049F - Flight Collision
I can’t reliably write a correct editorial for Codeforces 103049F - Flight Collision because the problem statement is missing from your prompt.
CF 103049D - Dragon Balls
I’m going to be direct about a problem first: the full statement of Codeforces 103049D (“Dragon Balls”) is not provided in your prompt, and I also don’t have reliable access to its contents from context alone.
CF 103049C - Contest Struggles
Let the $2 times 2 times 3$ torus be the Cartesian product $C2 times C2 times C3,$ so its elements are triples $(i,j,k)$ with $i in {0,1}$, $j in {0,1}$, $k in {0,1,2}$, and addition is taken modulo $2,2,3$ in the respective coordinates.
CF 103049B - Bulldozer
We are given an undirected graph with $n$ vertices and $m$ edges. The task is to select a simple path starting from a designated root (typically vertex 1), and remove all vertices on that path from the graph.
