Tourist level has still the same color as LGM in the chart:
You can make a mashup contest of problems you want to solve and send your solution in a group. Your code will be judged in a few minutes!
I tried a greedy solution for this problem:
1. If there exist a pair of adjacent vertices like $$$(u,v)$$$ such that $$$deg(u)\geq3$$$ and $$$deg(v)\geq3$$$, then remove the edge between $$$u$$$ and $$$v$$$.
2. Then, if there exist a pair of adjacent vertices like $$$(u,v)$$$ such that $$$deg(u)\geq3$$$ and $$$deg(v)\geq2$$$, then remove the edge between $$$u$$$ and $$$v$$$.
3. Then, if there exist a pair of adjacent vertices like $$$(u,v)$$$ such that $$$deg(u)\geq3$$$ and $$$deg(v)\geq1$$$, then remove the edge between $$$u$$$ and $$$v$$$.
At last, I add edges between the leaves of different components .
Why isn't it correct??

Given a graph G s.t. any cycle in G has length 3.
1)Find the maximum number of edges. 2)Find the maximum number of cycles.
Can someone compare atcoder contests and problem levels with codeforces contest and problem levels?
