The Travelling Salesman Problem is a classic optimization problem where a salesman must visit a set of cities exactly once and return to the starting city with the shortest possible route.
Involves finding the shortest possible route that visits each city exactly once and returns to the starting city
Considered a NP-hard problem, meaning there is no known efficient algorithm to solve it for large number of cities

The most difficult coding problems in the coding round were related to optimizing algorithms and handling complex data structures.
Optimizing algorithms for efficiency

Implementing dynamic programming solutions
Dealing with multi-threading and concurrency issues
I applied via LinkedIn and was interviewed before May 2023. There were 2 interview rounds.
Inheritance in Java allows a class to inherit attributes and methods from another class.
Inheritance is achieved using the 'extends' keyword in Java.
Subclasses can access the members of the superclass using inheritance.
Java does not support multiple inheritance, but a class can implement multiple interfaces.

A LinkedList is a data structure where each element points to the next element in the list.
LinkedLists are useful for dynamic data structures where the size of the list may change during runtime.
They can be singly linked or doubly linked, where each element points to the next or both the next and previous elements respectively.
Insertion and deletion operations are efficient in LinkedLists compared to arrays.
Example: A ...
Stack is a data structure that follows Last In First Out (LIFO) principle.
Elements are added and removed from the top of the stack.
Common operations include push (add element) and pop (remove element).
Stacks are used in programming for function calls, expression evaluation, and memory management.

2 coding questions (Problem statements) to be solved in 1 hour.
First question was easy. Based on loops, strings, array, mathematics,
The 2nd question was difficult and was based on Dynamic Programming.
List and tuple are both data structures in Python, but they have some differences.
Lists are mutable, while tuples are immutable.
Lists use square brackets [], while tuples use parentheses ().
Lists are typically used for collections of homogeneous items, while tuples are used for heterogeneous items.
Lists are usually used for sequences that will be modified, while tuples are used for sequences that will not be modified.

Pass statement skips the current iteration and continue statement skips the current iteration and moves to the next one.
Pass statement is used to do nothing and move to the next iteration in a loop.
Continue statement is used to skip the current iteration and move to the next one in a loop.
Pass statement is used when a statement is required syntactically but no action is needed.
Continue statement is used when a conditio...
No, continue statement can only be used inside loops.
The continue statement is used to skip the current iteration of a loop.
It cannot be used outside of a loop as there is no iteration to skip.
Attempting to use continue outside of a loop will result in a syntax error.
Global variables are accessible throughout the program, while local variables are only accessible within a specific function.
Global variables can be accessed and modified by any function or module in the program.
Local variables are declared within a specific function and can only be accessed within that function.
Global variables can cause naming conflicts and make debugging difficult.
Local variables are preferred for t...
Static variable is a variable that retains its value even after the function execution is completed.
Static variables are declared inside a function with the keyword 'static'.
They are initialized only once and retain their value throughout the program.
They have a default value of 0 if not initialized explicitly.
They are useful in situations where we need to maintain the state of a variable across function calls.
Polymorphism refers to the ability of an object to take on many forms. There are two types of polymorphism: compile-time and runtime.
Compile-time polymorphism is achieved through function overloading and operator overloading.
Runtime polymorphism is achieved through virtual functions and function overriding.
Example of compile-time polymorphism: function overloading - multiple functions with the same name but different p...
