Samsung Software Engineer Interview Questions, Process, and Tips

Demonetization problem refers to the sudden withdrawal of high-value currency notes from circulation.

• Demonetization can lead to cash shortages and economic disruption.

• It can also have long-term effects on the economy, such as increased digitization and reduced corruption.

• Examples of demonetization include India's 2016 demonetization of 500 and 1000 rupee notes and Zimbabwe's 2015 demonetization of its currency.

I rate myself 2 in C, 3 in C++ and 4 in DS.

• I have a good understanding of basic concepts in C and can write simple programs.

• I have worked on projects in C++ and have a decent knowledge of OOP concepts.

• I am comfortable with data structures like arrays, linked lists, stacks, and queues.

Storage classes in C define the scope and lifetime of variables.

• There are four storage classes in C: auto, register, static, and extern.

• Auto variables are local to a block and have automatic storage duration.

• Register variables are stored in CPU registers for faster access.

• Static variables have a lifetime throughout the program and are initialized only once.

• Extern variables are declared outside any function and can be a

C program to reverse a string in-place

• Use two pointers, one at the beginning and one at the end of the string

• Swap the characters at the two pointers and move the pointers towards each other until they meet

• Handle odd-length strings by leaving the middle character in place

Program to insert a node in linked list

• Create a new node with the given data

• Set the next pointer of the new node to the next pointer of the previous node

• Set the next pointer of the previous node to the new node

Program to find loop in linked list

• Use two pointers, slow and fast, to traverse the linked list

• If there is a loop, the fast pointer will eventually catch up to the slow pointer

• To find the start of the loop, reset the slow pointer to the head and move both pointers at the same pace

Quick sort is a divide and conquer algorithm that sorts an array by partitioning it into two sub-arrays.

• Choose a pivot element from the array

• Partition the array around the pivot element

• Recursively apply the above steps to the sub-arrays

• Combine the sorted sub-arrays to get the final sorted array

Heap sort is a comparison-based sorting algorithm that uses a binary heap data structure.

• Heap sort works by building a binary heap from the array to be sorted.

• The largest element is then swapped with the root node and removed from the heap.

• The heap is then restructured and the process is repeated until the array is sorted.

• Heap sort has a time complexity of O(n log n) and is not stable.

• It is often used in embedded syste...read more

C++ is a high-level programming language used for developing system software, application software, device drivers, and video games.

• C++ was developed by Bjarne Stroustrup in 1983.

• It is an extension of the C programming language.

• C++ supports object-oriented programming, generic programming, and low-level memory manipulation.

• It is widely used in industries such as finance, gaming, and operating systems development.

OOP stands for Object-Oriented Programming, a programming paradigm that focuses on objects and their interactions.

• OOP is based on the concepts of encapsulation, inheritance, and polymorphism.

• It allows for modular and reusable code.

• Examples of OOP languages include Java, C++, and Python.

Which software are you referring to?

• Please specify the software you are asking about

• Without context, it is impossible to answer this question

Late binding is a programming concept where the method or function to be executed is determined at runtime.

• Also known as dynamic binding or runtime binding

• Allows for greater flexibility in code execution

• Commonly used in object-oriented programming languages

• Example: virtual functions in C++

Virtual functions are functions that can be overridden by derived classes.

• Virtual functions are declared in a base class and can be overridden in a derived class.

• They allow for polymorphism, where a derived class can be treated as its base class.

• Virtual functions are called based on the actual object type, not the pointer or reference type.

• They are declared using the 'virtual' keyword in the base class and optionally o...read more

A friend class is a class that is granted access to the private and protected members of another class.

• A friend class is declared using the 'friend' keyword.

• A friend class can access private and protected members of the class that granted it friendship.

• Friendship is not mutual, meaning the friend class does not grant access to its own members.

• Friend functions can also be declared in a class to grant access to private a

++x is faster than x++ because it increments the value before using it.

• ++x increments the value before using it, while x++ increments the value after using it.

• ++x is faster because it saves the overhead of creating a temporary variable.

• In some cases, the difference in speed may be negligible and the choice between the two may depend on readability and coding standards.

A null object is an object that does not have a value or reference to any object.

• A null object is different from an object with a value of zero or an empty string.

• It is often used to represent the absence of an object or value.

• Null objects can be used to avoid null pointer exceptions in programming.

• It is a conceptual idea in programming and computer science.
