B2B, or business-to-business, refers to transactions between businesses, often involving wholesale or service providers.
B2B transactions typically involve larger quantities of goods or services.
Examples include manufacturers selling to wholesalers or retailers.
B2B companies often provide specialized services, like software solutions for other businesses.
The B2B market is generally characterized by longer sales cyc...
Faced a challenging client situation due to miscommunication, resolved it through proactive engagement and tailored solutions.
Identified the issue: A client was unhappy due to a misunderstanding about deliverables.
Engaged directly: Scheduled a meeting to discuss their concerns and expectations.
Clarified deliverables: Presented a detailed plan outlining what we could provide and timelines.
Tailored solutions: Offere...
Use binary search algorithm with slight modifications to handle rotated sorted array efficiently.
Find the pivot point where the array is rotated.
Determine which half of the array the target value lies in based on the pivot point.
Perform binary search on the appropriate half of the array.
Implement a generics method map in Java
Create a generic method that takes an array and a function as parameters
Use a lambda expression to apply the function to each element in the array
Return a new array with the transformed elements
Strong references prevent objects from being deallocated, while weak references allow for deallocation, avoiding memory leaks.
Strong Reference: Keeps an object in memory; e.g., 'let strongRef = someObject'.
Weak Reference: Does not keep an object in memory; e.g., 'weak var weakRef = someObject'.
Use Cases: Strong references are used for ownership, while weak references are used to avoid retain cycles.
Example of Reta...
Inheritance with prototypes allows objects to inherit properties and methods from other objects in JavaScript.
Create a constructor function for the parent object
Add properties and methods to the parent object's prototype
Create a constructor function for the child object
Set the child object's prototype to be an instance of the parent object
Closure in JS is when a function is able to remember and access its lexical scope even when it is executed outside that scope.
Closure allows a function to access variables from its outer function even after the outer function has finished executing.
Functions in JavaScript form closures, which means they 'remember' the variables in the scope where they were created.
Closures are commonly used in event handlers, call...
Design a calculator using OOP principles, focusing on classes, methods, and encapsulation.
Create a base class 'Calculator' with basic operations: add, subtract, multiply, divide.
Use inheritance to create specialized calculators, e.g., 'ScientificCalculator' for advanced functions like sin, cos.
Implement encapsulation by keeping internal state private and providing public methods for interaction.
Consider using inte...
Design a heap tree data structure
A heap is a complete binary tree where the value of each node is greater than or equal to the values of its children
There are two types of heaps: min heap (parent node is smaller than children) and max heap (parent node is larger than children)
Heap can be implemented using arrays where parent node at index i has children at indices 2i+1 and 2i+2
QA testing ensures software quality through systematic evaluation, identifying defects, and verifying functionality against requirements.
QA testing involves various methodologies like manual testing, automated testing, and performance testing.
Example: Manual testing involves testers executing test cases without automation tools.
Automated testing uses scripts and tools to execute tests, improving efficiency and cov...

- Q1. Input: “kitten%20pic.jpg” output: “kitten pic.jpg” %20 -> ‘ ‘ %3A -> ‘?’ %3D -> ‘:’ modify your input in place. no string library functions. void DecodeURL(string str
- Ans.
The function decodes a URL-encoded string by replacing specific characters with their corresponding symbols.
Iterate through each character in the input string
If the character is '%', check the next two characters to determine the replacement symbol
Replace the '%XX' sequence with the corresponding symbol
Continue until all occurrences of '%XX' are replaced
- Q2. Given an array, return true, if it can be partitioned into two subarrays whose sum of elements are same, else return false Example: Input: {5,1,5,11} Output: true (as it can be divided into {5,1,5} {11} wh...
- Ans.
Check if an array can be partitioned into two subarrays with equal sum.
Iterate through the array and calculate the total sum of all elements.
If the sum is odd, return false as it cannot be divided into two equal parts.
If the sum is even, try to find a subset with sum equal to half of the total sum.
Use dynamic programming or backtracking to find the subset sum.
- Q3. Briefly discussed about projects in resume and questions were completely related to projects mentioned
- Q4. Find out the maximum contiguous circular sum in array, array may contain positive as well as negative numbers?
- Ans.
The maximum contiguous circular sum in an array is the maximum sum that can be obtained by wrapping the array around in a circular manner.
To find the maximum contiguous circular sum, we can use Kadane's algorithm twice.
First, we find the maximum sum using Kadane's algorithm for the non-circular array.
Then, we find the maximum sum using Kadane's algorithm for the circular array by subtracting the minimum sum subarray fr...
- Q5. Given a binary tree, print sum of each level ?
- Ans.
Given a binary tree, print sum of each level
Use a breadth-first search (BFS) algorithm to traverse the tree level by level
Keep track of the sum of each level using a separate variable for each level
Print the sum of each level after traversing the entire tree
- Q6. Add two integers which cannot be stored even in long long int?
- Ans.
It is not possible to add two integers that cannot be stored even in long long int.
The maximum value that can be stored in long long int is 9,223,372,036,854,775,807.
Any two integers whose sum exceeds this value cannot be stored in long long int.
In such cases, a different data type or approach is required to handle the large numbers.
- Q7. Length of longest substring with no repeating character (Full running code)?
- Ans.
Find the length of the longest substring without any repeating characters.
Use a sliding window approach to iterate through the string.
Keep track of the characters seen so far using a set.
Update the maximum length of the substring whenever a repeating character is encountered.
- Q8. There is a function getWord() which takes word as input and checks whether word is present in the dictionary. Given a long word as input find all the meaning full ( i.e getWord() is true ) that can be made...
- Ans.
Find all meaningful words from a given input using a dictionary check.
Use a recursive approach to generate all possible substrings.
Check each substring with getWord() to verify if it's a valid word.
Example: For 'antin', valid words include 'a', 'an', 'ant', 'tin', 'in'.
Consider using a set to avoid duplicate entries in the result.
