To implement a queue using a stack, use two stacks and simulate the queue operations.
Use two stacks, one for enqueue operation and one for dequeue operation.
For enqueue operation, simply push elements onto the stack used for enqueueing.
For dequeue operation, if the dequeue stack is empty, pop all elements from enqueue stack and push onto dequeue stack.
Then pop from the dequeue stack to simulate dequeue operation.
A linked list is a data structure consisting of nodes where each node points to the next node in the sequence.

Initialize a head pointer to null
Add nodes by updating next pointers
Traverse the list by following next pointers

Observables and promises are both used for handling asynchronous operations in JavaScript.
Observables are used for handling multiple values over time, while promises are used for handling a single value at a time.
Observables can be cancelled, while promises cannot be cancelled.
Promises have a built-in mechanism for error handling using the catch method, while observables use the error callback function.
Observables are ...

Program to check if a string is an Anagram or not
Create a function that takes in two strings as input
Sort the characters in both strings and compare if they are equal
Return true if they are anagrams, false otherwise
To connect MongoDB with a database, you need to use the MongoDB URI and a MongoDB client library.
Use the MongoDB URI to specify the connection details such as host, port, username, password, and database name
Install a MongoDB client library like Mongoose for Node.js or pymongo for Python
Use the client library to establish a connection to the MongoDB database and perform CRUD operations
An event listener is a function that waits for a specific event to occur and then triggers a response.
Event listeners are commonly used in web development to handle user interactions like clicks, keypresses, etc.
They are attached to specific elements and listen for events to occur on those elements.
Once the event occurs, the listener executes a callback function to respond to the event.
Example: Adding a click event lis...
Polymorphism is the ability of a function or method to behave differently based on the object it is acting upon.
Polymorphism allows objects of different classes to be treated as objects of a common superclass.
There are two types of polymorphism: compile-time (method overloading) and runtime (method overriding).
Example: Inheritance in object-oriented programming languages like Java allows for polymorphism.
Use two pointers to swap characters in place
Initialize two pointers, one at the beginning of the string and one at the end
Swap characters at the two pointers and move them towards each other until they meet or cross
Repeat the process until the entire string is reversed
Use bitwise XOR operation to find the missing number in O(N) time complexity.
Iterate through the array and XOR all the elements with their indices and the array length.
The missing number will be the result of XORing all the elements with their indices and the array length.
