Implementing collections in Java involves using built-in classes like ArrayList, HashMap, and LinkedList.

• Use ArrayList for dynamic arrays

• Use HashMap for key-value pairs

• Use LinkedList for linked list implementation

C is faster than Python due to its lower-level nature and direct hardware access.

• C is a compiled language, while Python is an interpreted language.

• C code is directly translated into machine code, while Python code is executed line by line.

• C has direct access to hardware, while Python relies on external libraries for such access.

Python is a high-level, interpreted language known for its simplicity and readability, while C is a low-level, compiled language known for its speed and efficiency.

• Python is dynamically typed, while C is statically typed.

• Python has automatic memory management, while C requires manual memory management.

• Python is platform-independent, while C is platform-dependent.

• Python is commonly used for web development and data analysis, while C is often used for system programming and emb...read more

Implement a linked list data structure in a programming language.

• Create a Node class with data and a reference to the next node

• Implement methods to add, remove, and search for elements in the linked list

• Handle edge cases like adding to an empty list or removing the last element

Operations on Linked list include insertion, deletion, traversal, and searching.

• Insertion: Add a new node at the beginning, end, or middle of the linked list.

• Deletion: Remove a node from the linked list based on a given key or position.

• Traversal: Visit each node in the linked list to perform operations or display data.

• Searching: Find a specific node in the linked list based on a given key or value.
