You have an 8 litre jug full of water and two smaller jugs, one that contains 5 litres and the other 3 litres. None of the jugs have markings on them, nor do you have any additional measuring device.You have to divide the 8 litres of water equally between your two best friends, so that each gets 4 litres of water. How can you do this? ( **Logical )** > 2. Write algorithm to find the length of longest correctly formed parantheses sequence **(Algorithm)** > 3. Tell whether the given sql query will work or not **(Technical)** > 4. Various Oops concepts (multithreading, abstractions, interfaces) **( Technical )** > 5. Collections frameworks (Vectors, Hashmaps and Hash tables) **( Technical )** > 6. Design priciples(Singletons, Abstract factory) **( Techincal )** > 7. on paper, code optimization question using singleton, abstract and interfaces **( Technical )** > 8. PCCs trademarks question, finding faulty coin using a scale **( Logical )** > 9. Animal / Zoo program using interfaces and abstract classes **( Technical )** > 10. Some algorithm question like sorting **( Technical )** > 11. Data Structure(*), Problem Solving(*), Puzzles, Past Project(*), Spring, Algorithms(*), OOP and refactoring code. **( Random )** > 12. Basic Java question and some basic data structure questions. eg. how to check if a string is a palindrome. **( Technical )** > 13. Data structure algorithm questions and riddles **( Random )** > 14. Java core questions, Spring, 5 Puzzles, SQL, Code refactoring, Code analysis, Data structure basic Linked List, Hash Map, Hash Set **( Random )** #### What I can prepare based on the above list * [ ] Java Basics like JVM, JRE, JDK, EAR, WAR * [ ] Java 3 design patterns * [ ] Java oop, interfaces vs abstract classes * [ ] Java multithreading, synchronization * [ ] LinkedList implementation, Hashmaps * [ ] String buffer vs builder * [ ] Checked and unchecked exception * [ ] Types of sorting and efficient one based on big O * [ ] Basic coding exercises like a palindrome, prime number, anagrams, etc. * [ ] JS working, event loop, timeouts * [ ] Check for design patterns in JS * [ ] SQL queries, select statements, JOINS clauses like WHERE, GROUP BY, ORDER BY, etc. * [ ] Spring basics, spring-security, AOP definitions * [ ] React tutorial videos #### Preparation material * **SQL** for Beginners - * **SQL** - Group By, Order By, Having, Where - * **SQL** - Joins - * **SQL** - Normalization - ![](/files/-MVUcESGbktfWOyuYNGh) {% embed url="" %} ## Morgan Stanley * How you create a data structure that can give back with O(1) the highest item from a stack. --- # Agent Instructions This documentation is published with GitBook.
