Explain the concept of a binary tree and its traversal algorithms This is a technical question testing your understanding of data structures. Be clear and concise in your explanation. "A binary tree is a hierarchical data structure in which each node has at most two children, referred to as the left child and the right child. It’s commonly used in searching and sorting

4. algorithms. There are three primary ways to traverse a binary tree: 1. In-order Traversal: First, we visit the left subtree, then the root node, and finally the right subtree. This method is often used for binary search trees because it retrieves nodes in non-decreasing order. 2. Pre-order Traversal: We visit the root node first, then recursively visit the left subtree followed by the right subtree. This traversal is useful for creating a copy of the tree or prefix notation of an expression. 3. Post-order Traversal: In this method, we recursively visit the left subtree, then the right subtree, and finally the root node. Post-order traversal is commonly used to delete or free nodes in a tree, as it ensures children are processed before the parent node." Technical Questions These questions focus on assessing your proficiency in programming and computer science concepts. Expect questions on: Data structures (linked lists, stacks, queues) Algorithms (sorting, searching) Object-oriented programming concepts Database queries (SQL) Q4. What is the difference between a linked list and an array? Answer: Array: Fixed size, stored in contiguous memory locations, and supports random access. Linked List: Dynamic size, stored in non-contiguous memory locations, and requires sequential access. Q5. How would you reverse a linked list? Answer: prev = NULL, current = head next = NULL. 1. Initialize three pointers: 2. Traverse the list: Store current->next , and next. prev. in Set to current->next

5. one step ahead. Move prev and current 3. Update the head to prev Example Node* reverse(Node* head) { Node* prev = NULL; Node* current = head; Node* next = NULL; while (current != NULL) { next = current->next; current->next = prev; prev = current; current = next; } r e t u r n p r e v ; } Q6. How does a stack differ from a queue? Answer: push, pop. enqueue, dequeue. Stack: Follows LIFO (Last In, First Out). Operations: Queue: Follows FIFO (First In, First Out). Operations: Q7. Write a program to check for balanced parentheses using a stack. Answer: Logic: Push opening brackets onto the stack and pop when a closing bracket is encountered. The stack should be empty at the end if balanced. def is_balanced(expression): stack = [] for char in expression: if char in "({[": stack.append(char)

6. elif char in ")}]": if not stack: return False top = stack.pop() if (char == ")" and top != "(") or \ (char == "]" and top != "[") or \ (char == "}" and top != "{"): return False returnnot stack Q8. Explain the concept of OOPs and its four pillars. Answer: Encapsulation: Wrapping data and methods into a single unit (class). Abstraction: Hiding implementation details and showing only functionality. Inheritance: Acquiring properties of a parent class in a child class. Polymorphism: Performing a single action in different ways (e.g., method overloading, overriding). Q9. What is the difference between method overloading and method overriding? Answer: Method Overloading: Same method name, different parameters, happens at compile-time. Method Overriding: Same method name, same parameters in parent and child classes, happens at runtime. Q10. Write a SQL query to find the second-highest salary from the Employee table. Answer: SELECT MAX(salary) AS second_highest_salary FROM Employee WHERE salary < (SELECT MAX(salary) FROM Employee);

7. Q11. What is the difference between DELETE and TRUNCATE in SQL? Answer: clause, logs each row deletion, and is WHERE DELETE: Removes specific rows, can use a slower. TRUNCATE: Removes all rows, cannot use a deletions, and is faster. clause, does not log individual WHERE Q12. Explain Bubble Sort and its time complexity. Answer: Bubble Sort: Repeatedly compare adjacent elements and swap them if they are in the wrong order. Time Complexity: Best Case: (when the array is already sorted). O(n) Worst Case: . O(n^2) void bubbleSort(int arr[], int n) { for (int i = 0; i < n - 1; i++) { for (int j = 0; j < n - i - 1; j++) { if (arr[j] > arr[j + 1]) { int temp = arr[j]; arr[j] = arr[j + 1]; arr[j + 1] = temp; } } } } Q13.

Transport Layer: Provides end-to-end communication, ensuring reliable data transfer (e.g., TCP/UDP). 5. Session Layer: Manages and controls connections between devices, including session creation and termination.  . Presentation Layer: Translates data between application and network formats, ensuring proper encoding, encryption, and compression. 7. Application Layer: Interfaces with the user, providing services like email (SMTP), file transfer (FTP), and web browsing (HTTP). This model helps standardize networking processes and facilitates interoperability between devices and technologies. Q28. Explain the concept of DNS and how it works. DNS (Domain Name System) is a system that translates human-readable domain names (like www.example.com) into IP addresses (like 192.0.2.1), which computers use to identify each other on the network. How DNS works:

14. 1. User Request: When you type a domain name into your browser, the request is sent to a DNS resolver. The resolver is typically provided by your ISP or network. 2. Cache Check: The resolver first checks if it has the requested domain name in its cache (which stores recently resolved IP addresses for faster access). If found, the resolver returns the cached IP address. 3. Recursive Query: If the IP address is not cached, the resolver sends a recursive query to a root DNS server. This server doesn’t know the final IP but directs the query to the relevant TLD (Top-Level Domain) server based on the domain extension (like .com or .org). 4. TLD Server: The TLD server points to the authoritative DNS server for the specific domain. 5. Authoritative DNS Server: This server holds the final, accurate IP address of the domain. It returns the IP address to the resolver.  . Return to User: The resolver sends the IP address back to your device, allowing your browser to connect to the correct website. DNS makes the internet user-friendly by allowing users to use easily memorable domain names instead of complicated IP addresses.

Use Optional in Java 8+ to handle potentially null values more safely. Use exception handling (try-catch) if necessary. Wipro Accounts Interview Questions These questions are targeted at candidates applying for roles in the accounts department. Expect questions like: Q45. Explain the basic accounting principles. The basic accounting principles include: 1. Accrual Principle: Revenue and expenses are recorded when earned or incurred, not when cash is exchanged. 2. Consistency Principle: The same accounting methods must be used consistently from period to period. 3. Going Concern Principle: Assumes a business will continue operating indefinitely.

23. 4. Prudence (Conservatism) Principle: Avoids overestimating income or assets and underestimating liabilities. 5. Economic Entity Assumption: Separates the financial activities of the business from personal transactions.  . Matching Principle: Expenses should be recorded in the same period as the revenue they generate. 7. Cost Principle: Assets should be recorded at their original cost, not current market value.  . Full Disclosure Principle: Requires all relevant information to be disclosed in financial statements. 9. Time Period Principle: Divides a business’s activities into consistent time periods for reporting. 10. Materiality Principle: Small transactions that don't affect financial decisions may be ignored. Q46. How do you handle financial reconciliations? Handling financial reconciliations involves ensuring that the financial records of a business are accurate, consistent, and aligned with external sources of information, such as bank statements or vendor accounts. Here’s how you can effectively handle financial reconciliations: 1. Gather Relevant Documents: Start by collecting all necessary documents such as bank statements, credit card statements, receipts, and invoices. Ensure you have the full set of records for the reconciliation period. 2. Match Transactions: Compare the transactions recorded in the company’s books with those in the external sources (e.g., bank statements). Ensure that all entries from both sources match. 3. Identify Discrepancies: Look for any differences between the two sets of records. Discrepancies could arise due to timing differences (e.g., checks written but not cleared), missing entries, or errors in recording transactions. 4. Adjust Entries: If discrepancies are identified, make adjustments to the financial records, such as correcting errors or updating entries. For example, if a payment was made but not recorded, you would add that payment to the books. 5. Investigate Unreconciled Items: For any items that cannot be immediately reconciled, investigate further. This may involve contacting the bank or the relevant parties (e.g., vendors, customers) to clarify the discrepancies.  . Document Adjustments: Keep a record of all adjustments made during the reconciliation process. This documentation will help in auditing and provide a clear trail for future reference.

24. 7. Verify with Supporting Documents: Cross-check adjusted transactions with supporting documents, such as receipts, contracts, and invoices, to ensure accuracy.   . Reconcile Periodically: Perform reconciliations on a regular basis (e.g., monthly or quarterly) to catch discrepancies early, ensuring that financial records are always up-to- date. 9. Ensure Compliance: Ensure that the reconciliation process follows the company’s internal controls and complies with accounting standards (e.g., GAAP or IFRS). 10. Review and Report: After reconciliation, review the final reconciled accounts, and prepare reports for management. Any unresolved discrepancies should be flagged for further investigation. By following these steps, financial reconciliations can help ensure that your company's financial records are accurate, transparent, and reliable, leading to more informed decision- making.

You can install it using the appropriate programming language bindings (e.g., Java, Python). Write Test Scripts: Using Selenium’s WebDriver, you write test scripts that perform actions such as clicking buttons, entering text into forms, verifying page content, navigating through pages, and more. Execute Tests: Run the scripts on different browsers or on a remote server to simulate real- user interactions. Selenium can be integrated with tools like TestNG or JUnit for executing the test cases and generating reports.

25. Cross-Browser Testing: You can run the same tests on different browsers to ensure cross- browser compatibility. Integration with CI/CD: Selenium can Continuous Integration/Continuous Deployment (CI/CD) pipelines using tools like Jenkins, allowing for automated testing as part of the build and deployment process. be integrated into Q48. Explain the concept of test-driven development. Test-Driven Development (TDD) is a software development methodology in which tests are written before the actual code is developed. It follows a short, iterative cycle that encourages developers to write tests for a feature before writing the code that implements the feature. The TDD process typically follows three steps: 1. Write a Failing Test: Write a test for a new feature or functionality, ensuring that it initially fails because the code that makes it pass hasn’t been written yet. Example: A test that checks if a function correctly calculates the sum of two numbers. 2. Write the Minimum Code to Pass the Test: Write the simplest code that is necessary to pass the test. The goal is not to write the most efficient or complete code but to just make the test pass. Example: Write a function that calculates the sum of two numbers and returns the result. 3. Refactor the Code: Once the test passes, improve or refactor the code to make it cleaner and more efficient without changing its functionality. Example: Refactor the function to handle different data types or edge cases. This cycle is repeated for each new piece of functionality, ensuring that the codebase is always tested and that the functionality is being developed with test coverage in mind.
