- Q1. Types of waits statement in the selenium WebDriver
- Ans.
There are three types of waits in Selenium WebDriver: Implicit Wait, Explicit Wait, and Fluent Wait.
Implicit Wait: Waits for a certain amount of time before throwing an exception if the element is not found.
Explicit Wait: Waits for a certain condition to occur before proceeding further in the code.
Fluent Wait: Waits for a certain condition to occur with a polling frequency before proceeding further in the code.

- Q2. Explain hashmap with an example
- Ans.
Hashmap is a data structure that stores key-value pairs and provides constant time complexity for insertion, deletion and retrieval.
Hashmap uses a hash function to map keys to their corresponding values in an array.
Collisions can occur when two keys map to the same index, which can be resolved using techniques like chaining or open addressing.
Example: A hashmap can be used to store the frequency of words in a document,...

Myntra had conducted a coding test on campus before the start of the placement season with 2 questions, one on stack and other on DP.
Tips : For the test, the DP question asked was pretty standard, on Longest Common Subsequence. The question on stacks, I don't remember what it was but it was also pretty straight forward. For the test, I would recommend to solve problem from GFG. If they do come to resume shortlisting, they are looking for people who have done good projects and internships.
- Q1.
Longest Common Subsequence Problem Statement
Given two strings
STR1andSTR2, determine the length of their longest common subsequence.A subsequence is a sequence that can be derived from another sequen...
- Ans.
The task is to find the length of the longest common subsequence between two given strings.
Implement a function to find the longest common subsequence between two strings.
Use dynamic programming to solve this problem efficiently.
Iterate through the strings and build a matrix to store the lengths of common subsequences.
Return the length of the longest common subsequence found.

The interview started off with questions on my general interest in Software Development. The first round had two coding questions, I was supposed to write the code on paper.
For the questions, they asked me to code the solution first. And then gave a specific input and asked me to demonstrate step by step in my code, how it would lead to the correct answer.
Tips: It's ok if you can't code a general solution, if you can write a code which works for the particular input they have given then also it's ok with them. But be thorough with Data structures.
- Q1.
Add Two Numbers as Linked Lists
You are given two singly linked lists, where each list represents a positive number without any leading zeros.
Your task is to add these two numbers and return the sum as ...
- Ans.
Add two numbers represented as linked lists and return the sum as a linked list.
Traverse both linked lists simultaneously while keeping track of carry from previous sum
Create a new linked list to store the sum, updating the value and carry as needed
Handle cases where one linked list is longer than the other by adding remaining digits with carry

I wasn't asked to write any code in this interview. They asked me some questions on Machine Learning, because of my projects in them. Then they asked me if I knew graph algorithms. Since I knew BFS and DFS, I told them. They asked the difference between the two. Then they asked me if I knew how to find the shortest distance between two points in a graph. I didn't know Dijkstra's properly but I knew it worked on the greedy approach so was able to tell that. Then they asked me how would I find the second shortest path. I tried to answer it with the same greedy approach, but couldn't arrive at the complete solution.
Tips: They ask a tough theoretical question. It's ok if you don't know the answer, they only look for your approach.

Traverse the right subtree recursively
Repeat until all nodes have been visited
- Q5. Inorder Travesal of a tree without recursion(write the code)

The interviewer asked to put everything on the blackboard and write down the code of each and everything.
Question : Explain all the search algorithm you know with space and Time complexities.
Answer : Linear search : It is a sequential search algorithm where the entire array is traversed till the desired element is not found. Time complexity is O(N) and auxiliary space is O(1).
Binary search : In this algorithm, a sorted array is searched by repeatedly dividing the search interval in half.
Steps :
1. Initially the interval covers the whole array.
2. If the value to be searched is less than the item in the middle of the interval, narrow the interval to the lower half. Otherwise, narrow it to the upper half.
3. The process is repeated until the value is found or the interval is empty.
Time complexity is O(log n) and auxiliary space is O(1) in case of iterative implementation.
