Question 4
Which of the following algorithms is most suitable for finding the shortest path in a weighted graph with non-negative edge weights?
Question 5
Consider the following algorithm:
1. Select a 'pivot' element from the array
2. Partition the array into two subarrays: elements less than the pivot and elements greater than the pivot
3. Recursively apply the above steps to the subarrays
4. Combine the subarrays and the pivot into a sorted array
What is the average-case time complexity of this algorithm?
