What is the time complexity of Kruskal's algorithm?
Understand the Problem
The question is asking about the time complexity associated with Kruskal's algorithm, which is a method used to find the minimum spanning tree of a graph. We need to look into the steps and operations involved in the algorithm to explain its time complexity properly.
Answer
O(E log E)
The time complexity of Kruskal's algorithm is O(E log E), where E is the number of edges in the graph. This complexity arises from the sorting step of the edges, which dominates the overall time complexity.
Answer for screen readers
The time complexity of Kruskal's algorithm is O(E log E), where E is the number of edges in the graph. This complexity arises from the sorting step of the edges, which dominates the overall time complexity.
More Information
Kruskal's algorithm is commonly used to find the Minimum Spanning Tree (MST) of a graph. It uses a greedy approach to select edges in increasing order of their weights.
Tips
A common mistake is to misinterpret the sorting step, which is critical for understanding the time complexity.
