Final answer:
A flowchart can be a Hamilton circuit, Euler path, or Tree graph.
Step-by-step explanation:
A flowchart can be a(n)
- Hamilton circuit: A circuit that visits every vertex exactly once and returns to the starting vertex.
- Euler path: A path that visits every edge exactly once.
- Tree graph: A graph that does not contain any cycles.
Therefore, a flowchart can be a Hamilton circuit, an Euler path, or a Tree graph.
