Q1. 
Cycle Detection in a Singly Linked List
Determine if a given singly linked list of integers forms a cycle or not.
A cycle in a linked list occurs when a node's next points back to a previous node in the ...read more
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.

Questions on DBMS and OS were asked in this round

Q1. What is the difference between paging and segmentation?
Ans. 
Paging divides physical memory into fixed-size blocks, while segmentation divides logical memory into variable-size segments.
• Paging divides memory into fixed-size blocks called pages, while segmentation divides memory into variable-size segments.

• Paging allows for efficient use of physical memory by swapping pages in and out of RAM, while segmentation simplifies memory management for programs.

• Paging is more commonly use...read more

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

Q2. Explain bending moment diagram Say torsion and bending equation
Ans. 
Bending moment diagram shows variation of bending moment along the length of a beam. Torsion equation relates torque, polar moment of inertia, and radius. Bending equation relates moment, bending stress, and section modulus.
• Bending moment diagram displays the variation of bending moment along the length of a beam.

• Torsion equation: T/J = τ/R, where T is the torque, J is the polar moment of inertia, τ is the shear stress...read more

Q3. Explain stress strain curve
Ans. 
Stress strain curve shows the relationship between stress (force applied) and strain (resulting deformation) in a material.
• The curve typically consists of three main regions: elastic deformation, plastic deformation, and fracture.

• In the elastic region, the material deforms elastically and returns to its original shape when the stress is removed.

• The plastic region is where permanent deformation occurs, but the material ...read more

Q1. Different types of slab
Ans. 
Different types of slabs include one-way slab, two-way slab, flat slab, waffle slab, and ribbed slab.
• One-way slab: Supported by beams on two opposite sides.

• Two-way slab: Supported by beams on all four sides.

• Flat slab: No beams, directly supported by columns.

• Waffle slab: Consists of a grid of ribs and beams forming square or rectangular voids.

• Ribbed slab: Similar to waffle slab but with smaller voids and thicker ribs.

Q2. Types of piling in construction industries
Ans. 
There are several types of piling used in construction industries.
• Driven Piling - steel or concrete piles are driven into the ground using a pile driver

• Bored Piling - a hole is drilled into the ground and then filled with concrete and steel reinforcement

• Screw Piling - a screw-like pile is screwed into the ground using a hydraulic motor

• Sheet Piling - interlocking steel sheets are driven into the ground to form a barrier
