In a balanced binary search tree, what is the average case time complexity for insertion operations?
Select the answer:Select the answer
1 correct answer
A.
O(1)
B.
O(n)
C.
O(log n)
D.
O(n log n)
In a balanced binary search tree, the insertion operation involves traversing the tree to find the appropriate spot. Because the tree remains approximately balanced, the depth is proportional to log n, resulting in an average time complexity of O(log n) for the insertion.

Which design pattern is most suitable for decoupling the sender and receiver in a distributed systems architecture?
Select the answer:Select the answer
1 correct answer
A.
Proxy Pattern
B.
Observer Pattern
C.
Message Queue
D.
Singleton Pattern
The Message Queue pattern effectively decouples components by asynchronously transmitting messages between producers and consumers. This reduces direct dependencies in the system, making it more scalable and resilient to failures. It is especially suitable for distributed systems, where asynchronous communication is necessary to manage high loads and ensure fault tolerance.
