They took us to the lab for this on and we were each given a paper with a program on it. It was all mixed as in each person got a different paper, You have around an hour to finish coding. after which you have to explain your code. They also gave wrong or incorrect inputs and see how your code handles these exceptions.

Q1. 
Reverse the String Problem Statement
You are given a string STR which contains alphabets, numbers, and special characters. Your task is to reverse the string.
Example:
Input:
STR = "abcde"
Output:
"e...read more
Ans. 
Reverse a given string containing alphabets, numbers, and special characters.
• Iterate through the string from the end to the beginning and append each character to a new string.

• Use built-in functions like reverse() or StringBuilder in languages like Python or Java for efficient reversal.

• Handle special characters and numbers along with alphabets while reversing the string.

• Ensure to consider the constraints provided in th...read more

Q2. 
K Largest Elements Problem Statement
Given an unsorted array containing 'N' integers, you are required to find 'K' largest elements from the array and return them in non-decreasing order.
Input:
The fir...read more
Ans. 
Implement a function to find K largest elements in an unsorted array in non-decreasing order.
• Create a min heap of size K and insert the first K elements of the array

• For each remaining element, if it is larger than the root of the heap, replace the root with the element and heapify

• Finally, the heap will contain the K largest elements in non-decreasing order

Q3. 
Remove Character from String Problem Statement
Given a string str and a character 'X', develop a function to eliminate all instances of 'X' from str and return the resulting string.
Input:
The first lin...read more
Ans. 
Develop a function to remove all instances of a given character from a string.
• Iterate through the string and build a new string excluding the specified character.

• Use a StringBuilder or similar data structure for efficient string manipulation.

• Handle edge cases like empty string or character not found in the input string.

• Ensure the function completes within the given time constraint.

Ans. 
Print a triangle pattern of numbers based on a given number 'N'.
• Iterate through each row and column to determine the numbers to print

• Use a combination of spaces and numbers to align the pattern correctly

• Increment the numbers in each row based on the row number

Compared to the other round this is more tech oriented. Lot more tech questions. It is of normal difficulty and is not that hard to clear, you only need to know the basics.
Very basic of Data Structure and Oracle knowledge enough. Lots of simple questions from data structures(insert into heaps etc). They did not ask to write code for DS, but rather to explain the logic through diagrams. For some complicated question, they expect how much you brainstorm ideas in solving

Q1. 
Convert Binary Tree to Mirror Tree
Convert a given binary tree into its mirror tree, where the left and right children of all non-leaf nodes are interchanged.
Input:
An integer ‘T’ denoting the number o...read more
Ans. 
Convert a binary tree into its mirror tree by interchanging left and right children of non-leaf nodes.
• Traverse the tree in postorder fashion and swap the left and right children of each node.

• Use recursion to solve the problem efficiently.

• Modify the binary tree in place without creating a new tree.

Q2. 
Heap Sort Problem Statement
Given an array ARR consisting of N integers, your task is to use the Heap sort algorithm to arrange the array in non-decreasing order.
Input:
The first line of the input cont...read more
Ans. 
Implement the Heap sort algorithm to arrange an array in non-decreasing order.
• Implement the Heap sort algorithm to sort the given array in non-decreasing order

• Use a max heap to sort the array in non-decreasing order

• Time complexity of Heap sort is O(n log n)

Q3. What is indexing in the context of databases?
Ans. 
Indexing in databases is a technique used to improve the speed of data retrieval by creating a data structure that allows for quick lookups.
• Indexes are created on specific columns in a database table to speed up queries that search for data in those columns.

• Indexes work similar to the index of a book, allowing the database to quickly locate the desired data without having to scan the entire table.

• Examples of indexes in...read more

Q4. Which data structure is better for your use case: a B Tree or a Hash Table?
Ans. 
Hash Table is better for fast lookups and insertions, while B Tree is better for range queries and ordered traversal.
• Use Hash Table for fast lookups and insertions with O(1) average time complexity.

• Use B Tree for range queries and ordered traversal with O(log n) time complexity.

• Consider the size of the dataset and the specific operations needed to determine the best data structure.

The interviewer was really cool. He realized that I mostly work on java applications so he chose to ask me stuff related to that. He didn't want me to know the answer well but just wanted me to approach to it, maybe think more. He went through my resume back and forth and asked mostly about all my projects and their logic and how could I take them to the next level.
Tips: Be confident. Its okay not to know any answer, just try giving it a shot in the approach.

Q1. 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

Q2. What is the difference between 'final', 'finally', and 'finalize' in Java?
Ans. 
final is a keyword used to declare constants, finally is a block used in exception handling, and finalize is a method used for cleanup.
• final is a keyword used to declare constants in Java, meaning the value cannot be changed once assigned. Example: final int x = 10;

• finally is a block used in exception handling to ensure a piece of code is always executed, whether an exception is thrown or not. Example: try { // code } ...read more

Q3. What is the difference between the private and final access modifiers in Java?
Ans. 
Private restricts access to the class itself, while final prevents inheritance and method overriding.
• Private access modifier restricts access to the class itself, while final access modifier prevents inheritance and method overriding.

• Private members are only accessible within the same class, while final classes cannot be extended and final methods cannot be overridden.

• Example: private int num; - num can only be accesse...read more

Q4. What are the steps for establishing a JDBC connection?
Ans. 
Establishing a JDBC connection involves loading the driver, creating a connection, creating a statement, executing queries, and handling exceptions.
• Load the JDBC driver using Class.forName() method

• Create a connection using DriverManager.getConnection() method

• Create a statement using connection.createStatement() method

• Execute queries using statement.executeQuery() method

• Handle exceptions using try-catch blocks

Q5. What is JSON?
Ans. 
JSON is a lightweight data interchange format used to store and transmit data between a server and a web application.
• JSON stands for JavaScript Object Notation.

• It is easy for humans to read and write, and easy for machines to parse and generate.

• JSON is language-independent and can be used with any programming language.

• Example: {"name": "John", "age": 30}

• Example: [{"name": "Alice", "age": 25}, {"name": "Bob", "age": 35}

Q6. What do you know about garbage collection in Java?
Ans. 
Garbage collection in Java is the process of automatically managing memory by deallocating objects that are no longer needed.
• Garbage collection helps in preventing memory leaks by reclaiming memory used by objects that are no longer referenced.

• Java uses a garbage collector to automatically manage memory, unlike languages like C++ where memory management is manual.

• Garbage collection in Java can be triggered by calling S...read more

I wouldn't say it went great but it was fine. I did not think I would clear it as for most of the questions the interviewer seemed disappointed and wanted more out of me.
