Angular applications work by utilizing TypeScript to create components, services, and modules that interact with the DOM.
Angular applications are built using TypeScript, a superset of JavaScript.
Components are the building blocks of Angular applications, representing different parts of the UI.
Services are used to share data and functionality across components.
Modules help organize the application into cohesive blocks o...
Components and directives are key concepts in Angular framework for building dynamic web applications.
Components are the basic building blocks of Angular applications, representing a part of the user interface.
Directives are markers on a DOM element that tell Angular to attach a specific behavior to that element or transform it.
Components are directives with a template.
Examples: ngIf, ngFor, ngStyle, ngClass
Dependency injection in Angular is a design pattern where components are given their dependencies rather than creating them.
In Angular, dependencies are injected into a component's constructor using TypeScript.
This allows for better modularity, reusability, and testability of code.
Dependencies can be provided at the module level or at the component level.
Example: constructor(private userService: UserService) {}
To call an API in Angular, you can use the HttpClient module to make HTTP requests.
Import the HttpClientModule in your app module
Inject the HttpClient service in your component/service
Use HttpClient's methods like get(), post(), put(), delete() to make API calls
Subscribe to the Observable returned by the HTTP request to get the response data

Types of solutions include physical solutions, chemical solutions, and biological solutions.
Physical solutions involve changes in the physical state of matter, such as dissolving sugar in water.
Chemical solutions involve chemical reactions, such as mixing an acid and a base to form a salt and water.
Biological solutions involve living organisms, such as using bacteria to break down organic waste.

Polymorphism is the ability of an object to take on many forms. Encapsulation is the practice of hiding data and methods within a class. Inheritance is the ability of a class to inherit properties and methods from a parent class.
Polymorphism allows objects to be treated as if they are of different types.
Encapsulation helps to protect data from outside interference and misuse.
Inheritance allows for code reuse and promot...
Stacks are a data structure that follows the Last-In-First-Out (LIFO) principle. They are used to store and retrieve data in a specific order.
Stacks have two main operations: push (to add an element to the top) and pop (to remove the top element)
Examples of stacks include the call stack in programming languages, undo/redo functionality in text editors, and the back button in web browsers
C++ is better than C due to its object-oriented programming features and better memory management.

Python is easier to learn, has simpler syntax, and is more versatile than C++.
Python has a simpler syntax and is easier to read and write than C++.
Python is an interpreted language, which means it doesn't need to be compiled before running.
Python has a vast library of modules and packages that can be easily imported and used.
Python is more versatile than C++ and can be used for a wide range of applications, including w...
Find all possible combinations of 2 elements in an array of length N whose sum is 10.
Iterate through the array and for each element, check if there exists another element in the array whose sum is 10.
Use a nested loop to compare each element with every other element in the array.
Store the pairs of elements whose sum is 10 in a new array.
Return the array of pairs.
Linked list is better than array for dynamic memory allocation and insertion/deletion operations.
Linked list allows for dynamic memory allocation, while arrays have a fixed size.
Insertion and deletion operations are faster in linked list as compared to arrays.
Arrays have better cache locality and are faster for random access.
Linked list is used in applications like implementing stacks, queues, and hash tables.
Arrays ar...
Binary search finds the position of a target value within a sorted array. Merge sort and bubble sort are sorting algorithms.
Binary search: repeatedly divide the search interval in half until the target value is found or not found
Merge sort: divide the unsorted list into n sublists, repeatedly merge sublists to produce new sorted sublists until there is only 1 sublist remaining
Bubble sort: repeatedly swap adjacent eleme...
