"WebFind a cycle $c$ in $G$ and a path $\pi$ that connects two vertices of $c$ without using an edge of $c$. The path splits $c$ into two cycles $c_1$ and $c_2$. If both $c_1$ and $c_2$ are odd cycles, then the paths $c_1 \setminus \pi$ and $c_2 \setminus \pi$ are either both even or both odd. Hence $c$ is in this case even. " - Find minimum cycle in graph
