Selection sort is not suitable for _______ datasets as it performs a fixed number of comparisons and swaps.
- Large
- Randomized
- Small
- Sorted
Selection sort is not suitable for large datasets as it performs a fixed number of comparisons and swaps. Regardless of the input, it always performs the same number of operations, making it inefficient for large datasets.
You're developing software for a ride-sharing service. How might you use a queue to handle incoming ride requests and allocate drivers to passengers?
- Allocate drivers based on a first-come, first-served basis from the queue.
- Assign drivers based on random selection for variety.
- Implement a queue where the longest waiting driver is assigned to the next ride.
- Use a priority queue to allocate drivers based on passenger ratings.
In a ride-sharing service, using a queue for driver allocation involves assigning drivers on a first-come, first-served basis from the queue. This ensures fairness and efficiency in handling incoming ride requests.
The Edit Distance algorithm computes the minimum number of _______ operations required to transform one string into another.
- Addition
- Deletion
- Substitution
- All of the above
The Edit Distance algorithm considers three possible operations: addition, deletion, and substitution. It computes the minimum number of these operations required to transform one string into another, making option 4, "All of the above," the correct choice.
Arrays provide _______ access to elements, but inserting or deleting elements can be _______.
- Constant, complex
- Direct, inefficient
- Random, time-consuming
- Sequential, fast
Arrays provide sequential access to elements, meaning that elements are stored in contiguous memory locations. However, inserting or deleting elements in the middle of an array can be time-consuming and inefficient, as it may require shifting all subsequent elements.
In which scenario would you choose Dijkstra's algorithm over Bellman-Ford or Floyd-Warshall algorithms?
- In scenarios where the graph has cycles.
- When dealing with a graph with negative edge weights.
- When the graph has both positive and negative edge weights.
- When working with a graph with non-negative edge weights.
Dijkstra's algorithm is preferred over Bellman-Ford or Floyd-Warshall algorithms when working with a graph that has non-negative edge weights. Unlike Bellman-Ford, Dijkstra's algorithm does not handle negative weights and is more efficient in such scenarios.
BFS, nodes are visited level by level, starting from the _______ node.
- Intermediate
- Leaf
- Random
- Root
In BFS (Breadth-First Search), nodes are visited level by level, starting from the root node. The algorithm explores all nodes at the current level before moving to the next level.
Associativity plays a key role in optimizing Matrix Chain Multiplication by _______.
- Allowing reordering of matrix multiplication operations
- Ensuring the matrices are square matrices
- Ignoring the order of matrix multiplication
- Restricting the order of matrix multiplication
Associativity plays a key role in optimizing Matrix Chain Multiplication by allowing the reordering of matrix multiplication operations. This flexibility enables the algorithm to find the most efficient sequence of multiplications.
In the context of the Longest Increasing Subsequence problem, "increasing" refers to the sequence where each element is _______ than the previous one.
- Divisible
- Equal
- Larger
- Smaller
In the context of the Longest Increasing Subsequence problem, "increasing" refers to the sequence where each element is Larger than the previous one. The goal is to find the longest subsequence where each element is strictly increasing.
Breadth-First Search (BFS) is commonly used in _______ for finding the shortest path between two nodes.
- Game Development
- Image Processing
- Network Routing
- Sorting Algorithms
Breadth-First Search (BFS) is commonly used in network routing for finding the shortest path between two nodes. It explores nodes level by level, making it efficient for finding the shortest path in networks.
In the Knapsack Problem, what are the typical constraints that need to be considered?
- Height and Depth
- Length and Width
- Volume and Size
- Weight and Value
The typical constraints in the Knapsack Problem include the weight and value of the items. These constraints ensure that the selected items do not exceed the capacity of the knapsack while maximizing the total value.
