This round had 40 MCQ's followed by 2 questions of DS and Algo. The programming questions were preety standard and can be solved within 30 minutes.
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.
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.
Given a string str
and a character 'X', develop a function to eliminate all instances of 'X' from str
and return the resulting string.
The first lin...
Develop a function to remove all instances of a given character from a string.
Iterate through the string character by character and only add characters that are not equal to the given character to a new string.
Alternatively, use built-in string manipulation functions to remove all instances of the given character from the string.
Ensure the function handles edge cases such as empty strings or strings with no instances o...

This round had questions from DSA, OS, DBMS and Computer Networks. The programming question was quiet easy and I coded it preety fast after discussing the appropriate approach and complexity analysis.
You are provided with two singly linked lists containing integers, where both lists converge at some node belonging to a third linked list.
Your task is to determine t...
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
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...
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...
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...
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 ...
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...
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

A generic swap function swaps two values of any data type.
The function should take two parameters of any data type.
Use a temporary variable to store the value of one parameter.
Assign the value of the second parameter to the first parameter.
Assign the value of the temporary variable to the second parameter.
Search for an element in a rotated sorted linked list.
Find the pivot point where the list is rotated.
Divide the list into two sublists based on the pivot point.
Perform binary search on the appropriate sublist.
Handle edge cases such as empty list and list with only one element.
Search an element in a rotated sorted array
Find the pivot point where the array is rotated
Divide the array into two sub-arrays based on pivot point
Perform binary search on the appropriate sub-array
Repeat until element is found or sub-array size is 1
Find 5 missing numbers in an array of size 95 containing numbers in range 1 to 100.
Create a boolean array of size 100 and mark the present numbers
Iterate through the boolean array and find the missing numbers
Alternatively, use a HashSet to store the present numbers and find the missing ones
