Online Assessment via Hacker Rank. Coding + Aptitude
Selenium Framework is a test automation tool used for web applications.
It supports multiple programming languages like Java, Python, etc.
It allows for easy creation and execution of test cases.
It supports various browsers like Chrome, Firefox, etc.
It provides features like object identification, synchronization, and reporting.
It can be integrated with other tools like Jenkins for continuous integration.
Example: Seleniu...

End to end automation cycle involves automating the entire software development process from planning to deployment.
The cycle starts with requirements gathering and planning
Next, the code is developed and tested using automation tools
Continuous integration and delivery are used to deploy the code to production
Monitoring and feedback are used to improve the process
Examples of automation tools include Jenkins, Selenium,
Find median of 2 sorted arrays in O(log N) time complexity and O(1) space complexity
Use binary search to find the partition point in both arrays
Calculate the median based on the partition point and array sizes
Adjust the partition points based on the median value
Repeat until the partition points are at the median
Handle edge cases such as empty arrays and uneven array sizes
Anagram of strings in O(1) space complexity
Use a fixed size array of integers to store the frequency of characters in the first string
Iterate through the second string and decrement the frequency of each character in the array
If all the frequencies are zero, then the strings are anagrams
Return true or false accordingly
Level order traversal of a tree using Queue
Create a queue and add the root node to it
While the queue is not empty, remove the front node and print its value
Add the left and right child nodes of the removed node to the queue
Repeat until the queue is empty
Reverse level order traversal of a tree using Queue
Create a queue and push the root node into it
While the queue is not empty, pop the front node and push its children into the queue
Add the popped node to a stack
Once the queue is empty, pop elements from the stack and print them
BFS and DFS are graph traversal algorithms. BFS explores nodes level by level while DFS explores nodes depth by depth.
BFS uses a queue while DFS uses a stack or recursion.
BFS is optimal for finding shortest path while DFS is optimal for finding a path between two nodes.
BFS requires more memory as it stores all the nodes at each level while DFS requires less memory.
BFS can be used to find connected components while DFS
Find product of each element of an array except that element in O(N) time complexity without using / operation
Use prefix and suffix products
Multiply prefix and suffix products for each element to get the final product
Handle edge cases where array has 0 or 1 element separately
Recursively delete a linked list
Create a recursive function that takes the head of the linked list as input
Base case: if the head is null, return
Recursively call the function with the next node as input
Delete the current node
Recursively delete a linked list from the end.
Start from the head and recursively traverse to the end of the list.
Delete the last node and set the second last node's next pointer to null.
Repeat until the entire list is deleted.
Use a recursive function to implement the deletion process.
Recursively delete a tree by deleting all its child nodes and then the parent node.
Start from the leaf nodes and delete them first.
Then move up to the parent nodes and delete them.
Repeat until the root node is deleted.
Use post-order traversal to ensure child nodes are deleted before parent nodes.
Recursively delete elements from the end of an array.
Create a recursive function that removes the last element of the array.
Call the function recursively until the desired number of elements are removed.
Handle edge cases such as empty arrays and removing more elements than the array contains.
Floyd Warshall finds shortest path between all pairs of vertices while Djikstra finds shortest path from a single source.
Floyd Warshall is used for dense graphs while Djikstra is used for sparse graphs.
Floyd Warshall has a time complexity of O(n^3) while Djikstra has a time complexity of O((n+m)logn).
Floyd Warshall can handle negative edge weights while Djikstra cannot.
Floyd Warshall can detect negative cycles while Dj
There is no known algorithm to find shortest path in 2-D space in O(log N) time.
The best known algorithm for finding shortest path in 2-D space is Dijkstra's algorithm which has a time complexity of O(N^2).
Other algorithms like A* and Bellman-Ford have better time complexity but still not O(log N).
If the points are on a grid, Lee algorithm can be used which has a time complexity of O(N).
Design a system for putting newspapers using classes and functions
Create a Newspaper class with attributes like title, date, and content
Create a Publisher class with methods to publish and distribute newspapers
Create a Subscriber class with methods to subscribe and receive newspapers
Use inheritance to create different types of newspapers like daily, weekly, etc.
Implement a database to store newspaper information and ha
