Garbage collector identifies objects to pick based on their reachability.

• Garbage collector starts from a set of root objects and identifies all objects that are reachable from them.

• Objects that are not reachable are considered garbage and are eligible for collection.

• Reachability is determined by following object references from root objects.

• Objects that are referenced by other reachable objects are also considered reachable.

• Objects that are not referenced by any reachable obj...read more

Sorting a list of strings based on their occurrence count.

• Create a dictionary to store the count of each string.

• Use the dictionary to sort the list based on the count of occurrences.

• If two strings have the same count, sort them alphabetically.

• Return the sorted list.

Algorithm to find missing number in a sequence

• Use mathematical formula for arithmetic or geometric sequence

• For random sequence, use sorting and iteration

• Consider edge cases like empty sequence or multiple missing numbers

Design patterns are reusable solutions to common problems in software design. Some types include Singleton, Factory, Observer, and Strategy patterns.

• Singleton pattern ensures a class has only one instance and provides a global point of access to it.

• Factory pattern creates objects without specifying the exact class of object that will be created.

• Observer pattern defines a one-to-many dependency between objects so that when one object changes state, all its dependents are notif...read more

Lambda expressions in Java 8 for Sorting and PartitionBy

• Use Comparator interface with lambda expression for sorting

• Use Collectors.partitioningBy() method with lambda expression for PartitionBy

Prevent memory leaks by properly managing memory allocation and deallocation.

• Use smart pointers instead of raw pointers.

• Avoid circular references.

• Free memory when it is no longer needed.

• Use tools like valgrind to detect memory leaks.

• Avoid global variables.

• Use RAII (Resource Acquisition Is Initialization) technique.

• Avoid using malloc and free directly.

• Use a garbage collector if appropriate.

SQL indexes are stored in the database's file system.

• Indexes are stored in the same filegroup as the table or in a separate filegroup.

• They can be stored in the same physical file as the table or in a separate file.

• Indexes can also be stored in memory, such as in the buffer pool.

Bundling in MVC is needed to improve performance by reducing the number of HTTP requests.

• Bundling combines multiple files into a single file to reduce the number of HTTP requests.

• This improves performance by reducing the time it takes to load a page.

• Bundling also allows for minification, which reduces the size of the files being sent to the client.

• Examples of files that can be bundled include CSS, JavaScript, and images.

Memory management is the process of managing computer memory to allocate and deallocate memory resources.

• Memory management involves allocating memory to processes that need it and deallocating memory that is no longer needed.

• It also involves managing memory fragmentation and ensuring efficient use of memory.

• Examples of memory management techniques include paging, segmentation, and virtual memory.

• Memory leaks can occur when memory is not properly managed, leading to performanc...read more

Solid principles are a set of design principles for writing maintainable and scalable code.

• Solid principles apply to object-oriented programming.

• They help in writing code that is easy to maintain, extend and test.

• Examples of solid principles are Single Responsibility Principle, Open-Closed Principle, Liskov Substitution Principle, Interface Segregation Principle, and Dependency Inversion Principle.

Memory management in .NET

• Garbage Collector manages memory by freeing up unused objects

• Memory is allocated on the heap and managed by the CLR

• Finalizers are used to release unmanaged resources

• Memory leaks can occur if objects are not properly disposed

• Value types are stored on the stack and are automatically managed

A dictionary stores data in key-value pairs.

• Each key is unique and maps to a specific value.

• Keys are used to retrieve values from the dictionary.

• Data can be added, removed, or updated in the dictionary.

• Examples include Python's dict and Java's HashMap.

Software development lifecycles are a set of processes used to design, develop, and maintain software.
