Design patterns are reusable solutions to common problems in software design, while SOLID principles are guidelines for writing maintainable and scalable code.
Design patterns help in organizing code, improving code reusability, and making code more maintainable.
Examples of design patterns include Singleton, Factory, Observer, and Strategy.
SOLID principles consist of Single Responsibility, Open/Closed, Liskov Substituti...
To create a top down Unity application based on SOLID principles, start by designing separate classes for each game element and ensuring single responsibility, open/closed, Liskov substitution, interface segregation, and dependency inversion principles are followed.
Design separate classes for player, enemies, obstacles, etc.
Ensure each class has a single responsibility.
Use interfaces to define common behaviors for diff...

Full selectors select all descendants of a specified element, while partial selectors select only direct children.
Full selectors use a space between the parent and child elements, while partial selectors use the > symbol.
Full selectors are more general and can target multiple levels of descendants, while partial selectors are more specific and target only direct children.
Example of full selector: div p selects all

Heap sort is a comparison-based sorting algorithm that uses a binary heap data structure.
Heap sort works by building a binary heap from the array and then repeatedly extracting the maximum element and placing it at the end of the array.
The heap is maintained as a complete binary tree, where each parent node is greater than or equal to its children.
The time complexity of heap sort is O(n log n) and it is an in-place sor...

Formula to calculate number of squares that can fit inside a triangle
Calculate the area of the triangle and the area of the square
Divide the area of the triangle by the area of the square to get the number of squares that can fit inside the triangle
Formula: (h*b)/(a*a)
SVM is a machine learning algorithm used for classification and regression analysis.
SVM finds the best hyperplane that separates data into different classes.
It works by maximizing the margin between the hyperplane and the closest data points.
SVM can handle both linear and non-linear data using kernel functions.
It is widely used in image classification, text classification, and bioinformatics.
SVM has been shown to be ef...
Logistic regression is used for classification while linear regression is used for regression analysis.
Logistic regression predicts the probability of an event occurring, while linear regression predicts the value of a continuous variable.
Logistic regression uses a sigmoid function to map input values to a probability between 0 and 1.
Linear regression assumes a linear relationship between the independent and dependent ...
