Time complexity of graphs and trees is crucial for analyzing algorithms.

• Time complexity of graphs is often O(V + E) where V is the number of vertices and E is the number of edges.

• Time complexity of trees is often O(N) where N is the number of nodes.

• Traversing a graph or tree can have different time complexities based on the algorithm used, such as BFS or DFS.

• Example: BFS traversal of a graph has a time complexity of O(V + E).

Press tools are typically made from materials such as steel, aluminum, and carbide to withstand high pressure and wear.

• Steel is commonly used for its durability and strength

• Aluminum is used for its lightweight properties

• Carbide is used for its hardness and resistance to wear

POST is used to create a new resource, GET is used to retrieve data, and PUT is used to update an existing resource.

• POST method is used to create a new resource on the server

• GET method is used to retrieve data from the server

• PUT method is used to update an existing resource on the server

• POST requests are not idempotent, while GET and PUT requests are idempotent

TreeMap is a class in Java that implements the Map interface using a tree structure.

• TreeMap stores key-value pairs in a sorted order based on the natural ordering of keys or a custom Comparator.

• It allows for efficient retrieval, insertion, and deletion operations.

• Example: TreeMap treeMap = new TreeMap<>();

Inheritance in Java allows a class to inherit properties and behavior from another class.

• Inheritance is achieved using the 'extends' keyword in Java.

• Subclass inherits all non-private fields and methods from superclass.

• Subclass can override superclass methods to provide specific implementation.

• Superclass can be abstract, preventing instantiation of the class.

• Example: class Dog extends Animal { ... }
