Q1. 
Maximum Subarray Sum Problem Statement
Given an array arr of length N consisting of integers, find the sum of the subarray (including empty subarray) with the maximum sum among all subarrays.
Explanation...read more
Ans. 
Find the sum of the subarray with the maximum sum among all subarrays in a given array.
• Iterate through the array and keep track of the maximum sum subarray seen so far.

• Use Kadane's algorithm to efficiently find the maximum subarray sum.

• Handle cases where all elements are negative or array is empty.

• Example: For input arr = [-2, 1, -3, 4, -1], the maximum subarray sum is 4.

Your task is to determine t...read more
Ans. 
Find the node where two linked lists merge, return -1 if no merging occurs.
• Traverse both lists to find their lengths and the difference in lengths

• Move the pointer of the longer list by the difference in lengths

• Traverse both lists simultaneously until they meet at the merging point

Q2. Can you explain the concepts of multitasking and multiprogramming?
Ans. 
Multitasking involves executing multiple tasks simultaneously, while multiprogramming involves running multiple programs on a single processor.
• Multitasking allows multiple tasks to run concurrently on a single processor, switching between them quickly.

• Multiprogramming involves loading multiple programs into memory and executing them concurrently, utilizing idle CPU time efficiently.

• Examples of multitasking include runn...read more

Q3. What is the difference between a process and a program?
Ans. 
A process is an executing instance of a program, while a program is a set of instructions stored in the computer's memory.
• A program is a static set of instructions stored on disk, while a process is a dynamic instance of those instructions being executed in memory.

• Multiple processes can be running the same program simultaneously, each with its own memory space and resources.

• Processes have their own unique process ID (P...read more

Q4. What is the difference between a process and a thread?
Ans. 
A process is an instance of a program, while a thread is a unit of execution within a process.
• A process has its own memory space, while threads share the same memory space.

• Processes are independent and isolated, while threads can communicate and share resources.

• Creating a new process is more resource-intensive than creating a new thread.

• Processes have their own program counter, while threads share the same program coun...read more

Q5. What is the main difference between UNION and UNION ALL?
Ans. 
UNION combines and removes duplicate rows, UNION ALL combines without removing duplicates.
• UNION combines the result sets of two or more SELECT statements into a single result set

• UNION removes duplicate rows from the result set

• UNION ALL combines the result sets without removing duplicates

• UNION is slower than UNION ALL as it requires additional processing to remove duplicates

• Use UNION when you want to combine and remove ...read more

Q6. What are the advantages of using views in a database management system?
Ans. 
Views provide a virtual representation of data, offering advantages such as simplifying complex queries, enhancing security, and improving performance.
• Views simplify complex queries by predefining commonly used joins, filters, and aggregations.

• Views enhance security by allowing users to access only specific columns or rows of a table.

• Views improve performance by storing the results of complex queries, reducing the need...read more

Q7. What is the ARP protocol?
Ans. 
ARP stands for Address Resolution Protocol, used to map IP addresses to MAC addresses in a local network.
• ARP is used to find the MAC address of a device based on its IP address

• It operates at the data link layer of the OSI model

• ARP requests are broadcasted to all devices on the local network

• Example: When a device wants to communicate with another device on the same network, it uses ARP to find the MAC address of the des
