Prove undirected graph has <=2
components after removing one vertex
Analyze the prove undirected graph has <=2 components after removing one vertex.
Examples
Example 1
Input:
"test_input_1"
Output:
"output_1"
Example 2
Input:
"test_input_2"
Output:
"output_2"
Hints
Hint 1
Consider the definition of a connected component in an undirected graph and how removing a vertex affects it.
Hint 2
Explore the relationship between articulation points (or cut vertices) and the number of connected components in a graph.
Hint 3
Prove by contradiction: Assume removing a vertex results in more than 2 components, then analyze the implications on the original graph's structure.
