Answer conceptual true/false and caching questions
Technical Screening Questions
You will be presented with several quick technical screening questions. For each question, you must answer with either Yes or No and provide a brief, clear justification for your answer.
- Integer Representation: "A 64-bit integer type can represent twice as many distinct integer values as a 32-bit integer type."
- Caching and Eviction Policies:
- Describe an example workload where the Least Frequently Used (LFU) cache eviction policy performs better than the Least Recently Used (LRU) policy.
- Explain the difference between LFU and LRU using a non-technical analogy that a 3-year-old could understand.
- Asymptotic Complexity: "Binary search on a linked list has a time complexity of O(n log n)."
- Graphs: "Given N nodes, an acyclic graph has at most N-1 edges."
Please state any assumptions you make for your answers (e.g., directed vs. undirected graph, signed vs. unsigned integers for integer representation).
