Component interaction in Angular involves communication between components using various techniques like Input, Output, and services.
1. Parent to Child Communication: Use @Input() to pass data from a parent component to a child component.
Example: <child-component [data]='parentData'></child-component>
2. Child to Parent Communication: Use @Output() with EventEmitter to send data from a child componen...
Cells communicate between 2 sites through various signaling pathways, including direct cell-to-cell contact and chemical signaling.
Cells can communicate through direct cell-to-cell contact, such as gap junctions or cell adhesion molecules.
Cells can also communicate through chemical signaling, such as paracrine signaling (local signaling) or endocrine signaling (long-distance signaling).
Examples include neurotransm...
Sorting an array of strings can be done using various algorithms like QuickSort, MergeSort, or built-in functions.
Use built-in sort functions for simplicity: e.g., `array.sort()` in Python.
Consider case sensitivity: 'apple' < 'Banana' in ASCII, so use a case-insensitive sort if needed.
Sorting can be done lexicographically: e.g., ['banana', 'apple', 'cherry'] becomes ['apple', 'banana', 'cherry'].
For custom sort...
Factorial of a number is the product of all positive integers less than or equal to that number.
Factorial of 0 is 1 (0! = 1)
Factorial of a positive integer n is n * (n-1) * (n-2) * ... * 1
Factorial is denoted by the symbol '!'
Securing APIs involves implementing authentication, authorization, encryption, and input validation.
Implement authentication mechanisms like OAuth, JWT, or API keys
Use authorization techniques to control access to APIs based on roles and permissions
Encrypt sensitive data transmitted over the network using HTTPS
Validate and sanitize input to prevent common security vulnerabilities like SQL injection or cross-site s...
Maven clean and install are used to ensure a clean build and to install the project's artifacts into the local repository.
Maven clean removes all the compiled files and artifacts from the previous build.
Maven install compiles the source code, runs tests, and packages the project into a distributable format.
The artifacts are then installed into the local repository for future use by other projects.
Clean and install...
Future object in Java represents the result of an asynchronous computation.
It is used to retrieve the result of a computation that may not have completed yet.
It provides methods to check if the computation is done, retrieve the result, or cancel the computation.
It can be used with the Executor framework to execute tasks asynchronously.
Example: Future
future = executorService.submit(new MyTask());
The lifecycle of an object in Hibernate refers to the various states an object goes through during its existence in the Hibernate framework.
The object starts in the transient state when it is not associated with any session or database.
When the object is saved or persisted, it transitions to the persistent state.
In the persistent state, any changes made to the object are tracked and synchronized with the database.
...
Stack peek returns the top element without removing it, while stack pop returns and removes the top element.
Stack peek returns the top element of the stack without modifying the stack.
Stack pop returns and removes the top element of the stack.
Both methods operate on the top element of the stack.
Example: If the stack contains [1, 2, 3], peek will return 3 and pop will return 3 and modify the stack to [1, 2].

- Ans.
Separate positive and negative numbers from an array into two distinct arrays.
Iterate through the array and check each element's sign.
Create two new arrays: one for positive numbers and one for negative numbers.

A stack is a data structure that follows Last In First Out (LIFO) principle, used in various applications like function calls.
Function Call Management: Each function call is pushed onto the stack, and when it returns, it pops off the stack.
Undo Mechanism: Applications like text editors use stacks to manage undo operations, allowing users to revert to previous states.
Expression Evaluation: Stacks are used in parsing exp...
