This question evaluates system-design and algorithmic competencies, combining distributed-systems concepts — high availability, low-latency architecture, scalability levers, and fault-tolerance mechanisms — with practical binary-tree traversal and time–space complexity analysis.
Scenario
Round covering distributed-system design and algorithm implementation.
Question
Design a highly available, low-latency distributed order-processing system. Explain architecture, scalability levers, and fault-tolerance mechanisms. Implement LeetCode 987 ‘Vertical Order Traversal of a Binary Tree’ and analyze its time–space complexity.
Hints
Explain component interactions clearly; for LC987 discuss traversal strategy and sorting keys.
