Tip 1: Database Concepts: I refreshed my knowledge of database management systems, SQL queries, normalization, and database design principles. Understanding how to work with databases is crucial for developing applications with efficient data storage and retrieval.
Tip 2: Algorithms: I studied standard algorithms such as sorting, searching, and graph traversal algorithms (e.g., BFS and DFS). I also explored algorithmic paradigms like dynamic programming and greedy algorithms to approach different problem-solving scenarios.
Tip 3: System Design: I delved into system design principles, understanding how to design scalable, efficient, and reliable software systems. I studied concepts like distributed systems, database design, and caching to prepare for system design interviews.
Tip 1: Use keywords from the job description to optimize your resume for applicant tracking systems (ATS) used by many companies to screen resumes.
Tip 2: Keep your resume concise, use a clean and professional format, and proofread carefully for errors or inconsistencies. By tailoring your resume and highlighting your accomplishments, you can make a strong impression on potential employers and increase your chances of getting noticed for the job you desire.
Do you think that a huge increase in the demand for and production of AI tools is dangerous to humans?



Use zero-based indexing for the vertices.
The given graph doesn’t contain any self-loops.
Step 1: Perform a depth-first search on the reversed graph and store the order of the visited vertices.
Step 2: Perform a depth-first search on the original graph, starting from each vertex in reverse order.
Step 3: Identify strongly connected components by grouping mutually reachable vertices.



Let the given string be “(()())((”.
Here the valid parentheses substrings are: “()”, “()” and “(()())”. Out of these the longest valid string is “(()())” which has a length 6.
Step 1: Initialize variables and the stack.
Step 2: Iterate through the string, using the stack to track opening parentheses.
Step 3: Calculate the length of each valid substring encountered and update the maximum length.
Step 4: Return the maximum length as the result.
