Ans. 
Detect if a singly linked list forms a cycle by checking if a node's next points back to a previous node.
• Traverse the linked list using two pointers, one moving one step at a time and the other moving two steps at a time.

• If the two pointers meet at any point, it indicates the presence of a cycle in the linked list.

• To optimize space complexity, use constant extra space by modifying the linked list nodes.

Q2. What do you mean by FCFS (First-Come, First-Served)?
Ans. 
FCFS (First-Come, First-Served) is a scheduling algorithm where tasks are executed in the order they arrive.
• Tasks are processed based on their arrival time, with the first task arriving being the first to be executed.

• It is a non-preemptive scheduling algorithm, meaning once a task starts, it runs to completion without interruption.

• FCFS is simple to implement but may lead to longer waiting times for tasks that arrive la...read more

Q3. What is the difference between normalization and denormalization in database management systems?
Ans. 
Normalization is the process of organizing data in a database to reduce redundancy and improve data integrity, while denormalization is the process of intentionally introducing redundancy to improve query performance.
• Normalization involves breaking down a table into smaller tables and defining relationships between them to reduce redundancy.

• Denormalization involves combining tables and duplicating data to improve query...read more
