Flattening JSON in Node.js involves converting nested objects into a single-level object with dot notation keys.
Use recursion to traverse nested objects and build a flat structure.
Example: { a: { b: 1 } } becomes { 'a.b': 1 }.
Utilize a helper function to manage the current path as you iterate.
Consider edge cases like arrays and null values.
Optimize by avoiding unnecessary object copies.
In Python, an object is an instance of a class that encapsulates data and behavior.
Everything in Python is an object, including functions and classes.
Objects have attributes (data) and methods (functions) associated with them.
Example: Creating a simple class and object: class Dog: def bark(self): return 'Woof!' my_dog = Dog() my_dog.bark() # Outputs: 'Woof!'
Objects can be mutable (like lists) or immut...
Classes in Python are blueprints for creating objects, encapsulating data and behavior in a structured way.
Classes define a new data type that can have attributes (data) and methods (functions).
Example: class Dog: def bark(self): return 'Woof!'
Instances of classes are created using the class name followed by parentheses.
Example: my_dog = Dog() creates an instance of the Dog class.
Classes support inheritance, allow...
Program to reserve a string without using inbuilt methods in JavaScript
Use two pointers to swap characters at the beginning and end of the string until they meet in the middle
Create a function that takes a string as input and returns the reversed string
Example: Input 'hello', Output 'olleh'
Implement Traffic Light functionality using HTML+CSS+Vanilla Javascript
Create HTML elements for the traffic light
Use CSS to style the elements to represent the different lights (red, green, yellow)
Use Vanilla Javascript to toggle the lights based on the specified time intervals
The Two Sum problem involves finding two numbers in an array that add up to a specific target sum.
Use a hash map to store numbers and their indices for quick lookup.
Iterate through the array, checking if the complement (target - current number) exists in the hash map.
Example: For nums = [2, 7, 11, 15] and target = 9, return indices [0, 1] since 2 + 7 = 9.
Time complexity is O(n) due to a single pass through the arr...
LSTM (Long Short-Term Memory) is a type of recurrent neural network that is capable of learning long-term dependencies.
LSTM is designed to overcome the vanishing gradient problem in traditional RNNs.
It has three gates: input gate, forget gate, and output gate, which control the flow of information.
LSTM is commonly used for time series forecasting, such as predicting stock prices or weather patterns.
To use LSTM for...
Encoder-decoder is a neural network architecture used for tasks like machine translation and image captioning.
Encoder processes input data and generates a fixed-length representation
Decoder takes the representation and generates output data
Commonly used in tasks like machine translation (e.g. translating English to French) and image captioning
Cross entropy loss is used in classification because it penalizes incorrect classifications more heavily, making it more suitable for classification tasks compared to SSE.
Cross entropy loss is more suitable for classification tasks because it penalizes incorrect classifications more heavily than SSE.
Cross entropy loss is commonly used in scenarios where the output is a probability distribution, such as in multi-cl...
RNN is a type of neural network that can process sequential data by retaining memory of previous inputs.
RNN stands for Recurrent Neural Network.
It has loops in the network, allowing information to persist.
RNNs are commonly used in natural language processing and time series analysis.
Example: Predicting the next word in a sentence based on previous words.
