Multi tasking, multi processing, and multi programming are different approaches to managing tasks in an operating system.
Multi tasking allows multiple tasks to run concurrently on a single processor.
Multi processing involves multiple processors running tasks simultaneously.
Multi programming allows multiple programs to be loaded into memory and executed concurrently.
Examples of multi tasking operating systems include Wi...
Memory allocation refers to the process of assigning memory to programs during runtime.
Stack allocation is done automatically and is limited in size.
Heap allocation is done manually and is larger in size.
Stack memory is used for local variables and function calls.
Heap memory is used for dynamic memory allocation.
Memory leaks can occur if heap memory is not properly managed.
Use a shared variable and synchronization mechanisms to ensure natural order printing of numbers.
Create two threads, one for printing even numbers and the other for printing odd numbers.
Use a shared variable to keep track of the current number to be printed.
Implement synchronization mechanisms like locks or semaphores to ensure only one thread can access the shared variable at a time.
Each thread should check if it is i...
Printing a matrix in spiral order
Start from the first element and print it
Move in a spiral order towards the center of the matrix
Repeat until all elements are printed
Thread class and Runnable Interface are used for multithreading in Java.
Thread class is a predefined class in Java that provides methods to create and control threads.
Runnable interface is used to define a task that can be executed by a thread.
Thread class implements Runnable interface.
Thread class provides more control over threads than Runnable interface.
Example: Thread t = new Thread(new MyRunnable()); t.start();
Exa...
Linked List is a dynamic data structure while ArrayList is a static data structure.
Linked List is best for frequent insertion and deletion operations.
ArrayList is best for frequent access operations.
Linked List uses more memory than ArrayList.
ArrayList is faster than Linked List for accessing elements.
Use Linked List when you need to frequently add or remove elements from the list.
Use ArrayList when you need to frequen

Round duration - 65 Minutes
Round difficulty - Medium
This was an online proctured coding test where we had 2 questions to solve under 65 minutes. Both the questions were of difficulty Medium to Hard.
Given an integer array, your objective is to change all elements to the same value, minimizing the cost. The cost of changing an element from x
to y
is defined ...
Find the minimum cost to make all elements of an array equal by changing them to a common value.
Calculate the median of the array and find the sum of absolute differences between each element and the median.
Sort the array and find the median element, then calculate the sum of absolute differences between each element and the median.
If the array has an even number of elements, consider the average of the two middle elem
Given a pattern as a string and a set of words, determine if the pattern and the words list align in the same sequence.
T (number of test cases)
For each test ca...
Given a pattern and a list of words, determine if the words align with the pattern.
Create a mapping between characters in the pattern and words in the list.
Check if the mapping preserves the order of characters in the pattern.
Return 'True' if the sequence of words matches the order of characters in the pattern, else return 'False'.
Round duration - 50 Minutes
Round difficulty - Medium
This round had 2 algorithmic questions in which I first had to explain my approach with proper complexity analysis and then code the solution in any preferred IDE.
You are given an integer array 'ARR' of size 'N' and an integer 'S'. Your task is to find and return a list of all pairs of elements where each sum of a pair equals 'S'.
Find pairs of elements in an array that sum up to a given value, sorted in a specific order.
Iterate through the array and for each element, check if the complement (S - current element) exists in a hash set.
If the complement exists, add the pair to the result list.
Sort the result list based on the criteria mentioned in the question.
Return the sorted list of pairs.
Given a specified number of intervals, where each interval is represented by two integers denoting its boundaries, the task is to merge all overlapping interv...
Merge overlapping intervals and return sorted list of merged intervals.
Iterate through intervals and merge overlapping ones
Sort merged intervals based on starting times
Handle edge cases like empty input or single interval
Example: Input - [[1,4], [3,5], [6,8], [10,12], [8,9]], Output - [[1,5], [6,9], [10,12]]
Round duration - 60 Minutes
Round difficulty - Medium
This round had 1 standard coding question followed by some questions from OS and at last I was also asked some questions related to Statistics and Probability.
You are given a N x M
matrix of integers. Your task is to return the spiral path of the matrix elements.
The first line contains an integer 'T' which denotes the nu...
The task is to return the spiral path of elements in a given matrix.
Iterate through the matrix in a spiral path by adjusting the boundaries at each step.
Keep track of the direction of traversal (right, down, left, up) to cover all elements.
Handle edge cases such as when the matrix is a single row or column.
Implement the spiral path traversal algorithm efficiently to meet the time limit.
Ensure to print the elements in t
Use multiple threads to print numbers from 1 to 100 in an optimized approach.
Divide the range of numbers (1-100) among the threads to avoid overlap.
Use synchronization mechanisms like mutex or semaphore to ensure orderly printing.
Consider using a shared variable to keep track of the current number being printed.
Multitasking refers to the ability of an operating system to run multiple tasks concurrently, while multithreading involves executing multiple threads within a single process.
Multitasking allows multiple processes to run simultaneously on a single processor, switching between them quickly.
Multithreading enables a single process to execute multiple threads concurrently, sharing resources like memory and CPU time.
