- Q1. What are closures in javascript
- Ans.
Closures in JavaScript are functions that have access to variables from their outer scope even after the outer function has finished executing.
Closures allow for maintaining state in an asynchronous environment
They are created whenever a function is defined within another function
Example: function outerFunction() { let outerVar = 'I am outer'; return function innerFunction() { console.log(outerVar); }; }

- Q1. Is NaN === NaN
- Ans.
In JavaScript, NaN is not equal to itself, so NaN === NaN evaluates to false.
NaN stands for 'Not-a-Number' and is a special value in JavaScript.
According to the IEEE floating-point standard, NaN is not equal to any value, including itself.
Example: console.log(NaN === NaN); // false
To check if a value is NaN, use the isNaN() function: isNaN(NaN); // true

Use the Sieve of Eratosthenes algorithm for better efficiency
Optimize by only checking up to the square root of N for divisors

Technical round with questions mainly on Java and OOPS concepts.
- Q1. What is the difference between static methods and instance methods in Java?
- Ans.
Static methods belong to the class itself, while instance methods belong to individual objects of the class.
Static methods are called using the class name, while instance methods are called using object references.
Static methods cannot access instance variables directly, while instance methods can access both static and instance variables.
Static methods are shared among all instances of the class, while instance method...
- Q2. What is the difference between an abstract class and an interface in Java?
- Ans.
Abstract class can have both abstract and non-abstract methods, while interface can only have abstract methods.
Abstract class can have constructors, member variables, and methods with implementation.
Interface can only have abstract methods and constants.
A class can implement multiple interfaces but can only extend one abstract class.
Example: Abstract class - Animal with abstract method 'eat', Interface - Flyable with m...
- Q3. What is the difference between ClassNotFoundException and NoClassDefFoundError in Java?
- Ans.
ClassNotFoundException occurs when a class is not found during runtime, while NoClassDefFoundError occurs when a class was found during compilation but not during runtime.
ClassNotFoundException is a checked exception, while NoClassDefFoundError is an Error.
ClassNotFoundException occurs when a class is not found at runtime, usually due to a missing classpath or incorrect class name.
NoClassDefFoundError occurs when a cla...
- Q4. What is the difference between an Error and an Exception in Java?
- Ans.
Error is a serious issue that cannot be handled at runtime, while Exception is a recoverable issue that can be caught and handled.
Error is a subclass of Throwable and is usually caused by the environment or system, such as running out of memory or stack overflow.
Exception is also a subclass of Throwable but is caused by the application code, such as invalid input or file not found.
Errors are unchecked and are not meant...
- Q5. What is SerialVersionUID in Java?
- Ans.
SerialVersionUID is a unique identifier used by Java to ensure the compatibility of serialized objects.
SerialVersionUID is a static final long variable in a class that implements Serializable interface.
It is used to ensure that the serialized object can be deserialized correctly even if the class definition has changed.
If the SerialVersionUID of the serialized object does not match the one in the class, an InvalidClass...
- Q6. What are the requirements for creating an immutable class in Java?
- Ans.
Requirements for creating an immutable class in Java
Make the class final so it cannot be extended
Make all fields private and final
Do not provide setter methods, only getter methods
Ensure that mutable objects are not returned in getter methods
Override equals() and hashCode() methods for proper comparison
Consider making defensive copies of mutable fields in constructor or getter methods

Interview Questionnaire
9 Questions
- Q1. Questions related to the work done at my previous company
- Q2. Find if a given directed graph is cyclic or not
- Ans.
To check if a directed graph is cyclic or not
Use Depth First Search (DFS) algorithm to traverse the graph
Maintain a visited set to keep track of visited nodes
Maintain a recursion stack to keep track of nodes in the current DFS traversal
If a node is visited and is already in the recursion stack, then the graph is cyclic
If DFS traversal completes without finding a cycle, then the graph is acyclic
- Q3. You have a stream of bytes from which you can read one byte at a time. You only have enough space to store one byte. After processing those bytes, you have to return a random byte. Note: The probability of...
- Ans.
Return a random byte from a stream of bytes with equal probability.
Create a variable to store the count of bytes read
Create a variable to store the current random byte
For each byte read, generate a random number between 0 and the count of bytes read
If the random number is 0, store the current byte as the random byte
Return the random byte
- Q4. Find if a given Binary Tree is BST or not
- Ans.
Check if a binary tree is a binary search tree or not.
Traverse the tree in-order and check if the values are in ascending order.
For each node, check if its value is greater than the maximum value of its left subtree and less than the minimum value of its right subtree.
Use recursion to check if all nodes in the tree satisfy the above condition.
- Q5. Devise an algorithm to determine the Nth-to-Last element in a singly linked list of unknown length. If N = 0, then your algorithm must return the last element. You should parse the list only once
- Ans.
Algorithm to find Nth-to-Last element in a singly linked list of unknown length
Traverse the list and maintain two pointers, one at the beginning and one at Nth node from beginning
Move both pointers simultaneously until the second pointer reaches the end of the list
The first pointer will be pointing to the Nth-to-Last element
If N=0, return the last element
Parse the list only once
- Q6. Given an array of integers, print all possible permutations. Also explain your approach
- Ans.
Print all possible permutations of an array of integers
Use recursion to swap elements and generate permutations
Start with the first element and swap it with each subsequent element
Repeat the process for the remaining elements
Stop when all elements have been swapped with the first element
Print each permutation as it is generated
- Q7. Design a Stack DS that also prints in O(1) the minimum element you pushed in the stack
- Ans.
Design a stack that prints the minimum element pushed in O(1)
Use two stacks, one for storing elements and another for storing minimums
When pushing an element, compare it with the top of minimum stack and push the smaller one
When popping an element, pop from both stacks
To get the minimum element, just return the top of minimum stack
- Q8. Given a linked list with loop, how would you find the starting point of the loop ?
- Ans.
To find the starting point of a loop in a linked list, use Floyd's cycle-finding algorithm.
Use two pointers, one moving at twice the speed of the other.
When they meet, move one pointer to the head of the list and keep the other at the meeting point.
Move both pointers one step at a time until they meet again, which is the starting point of the loop.
- Q9. Find a number a matrix mat[m][n] where all the rows and columns are sorted non-decreasingly. What will be the complexity of the solution
- Ans.
To find a number in a matrix where all rows and columns are sorted non-decreasingly. Complexity of the solution.
Use binary search to find the number in each row and column
Start from the top-right corner or bottom-left corner to optimize search
Time complexity: O(m log n) or O(n log m) depending on the starting corner

- Q1. Binary search question on array
- Ans.
Binary search is an efficient algorithm for finding an item from a sorted array by repeatedly dividing the search interval in half.
1. Binary search requires a sorted array to function correctly.
2. It works by comparing the target value to the middle element of the array.
3. If the target value is less than the middle element, search the left half; if greater, search the right half.
4. Repeat the process until the target ...

- Q1. What is structure padding?
- Ans.
Structure padding is the insertion of unused bytes between structure members to align them on memory boundaries.
Padding is added to ensure that each member of a structure starts at a memory address that is a multiple of its size.
Padding is compiler-dependent and can vary between different platforms and architectures.
Padding can affect the size of a structure and the performance of the program.
Example: struct example { ...
