How is the graph data structure different from the tree data structure? a) Trees do not allow cycles, graphs may contain cycles b) Graphs cannot represent hierarchical data, trees can c) Graphs have a root node, trees do not d) Trees are a type of graph with specific properties.
Understand the Problem
The question is asking for a comparison between graph data structures and tree data structures, specifically focusing on their defining characteristics and differences.
Answer
Trees do not allow cycles, graphs may contain cycles.
Trees do not allow cycles, graphs may contain cycles.
Answer for screen readers
Trees do not allow cycles, graphs may contain cycles.
More Information
Trees, as a subset of graphs, are acyclic and specifically structured with parent-child relations, unlike graphs which may contain cycles and lack a singular hierarchical structure.
Tips
A common mistake is to assume all graphs cannot have cycles; trees are an exception as they form acyclic graphs.
