Question 1
What data structure does Dijkstra's Algorithm use for selecting the next vertex?
- Array
- Min-Heap
- Stack
💡 Hint: Consider which data structure allows for quick access to the smallest value.
Question 2
Heap violations are fixed upwards when:
- True
- False
💡 Hint: Think about the implications of increasing a node's value relative to it parent.

Question 1
Using the graph defined by vertices 1-4 and edges (1-2, cost 4), (1-3, cost 1), (2-4, cost 1), (3-4, cost 5). Demonstrate the application of Dijkstra’s Algorithm starting from vertex 1.
💡 Hint: Trace the path carefully, recording minimum distances achieved.
Question 2
Describe the implications of using an array versus a heap for implementing Dijkstra’s algorithm in terms of time complexity and performance.
💡 Hint: Compare the efficiency by considering retrieval of the minimum element.
