To find the binary representation of a number, convert the number to binary by dividing it by 2 and keeping track of the remainders.
Start by dividing the number by 2 and noting the remainder
Continue dividing the quotient by 2 until the quotient is 0
Write down the remainders in reverse order to get the binary representation
For example, the binary representation of 10 is 1010 (10 divided by 2 is 5 with a remainder o...
Swapping two variables can be done using a temporary variable, arithmetic operations, or bitwise XOR.
Using a temporary variable: Example: int a = 5, b = 10; int temp = a; a = b; b = temp;
Using arithmetic operations: Example: int a = 5, b = 10; a = a + b; b = a - b; a = a - b;
Using bitwise XOR: Example: int a = 5, b = 10; a = a ^ b; b = a ^ b; a = a ^ b;
Predicting y for a given x involves using statistical or machine learning models to establish a relationship between the variables.
Identify the relationship: Use regression analysis to find how y changes with x.
Model selection: Choose a model (e.g., linear regression, decision trees) based on data characteristics.
Training the model: Fit the model using historical data to learn the relationship.

- Q1. Explain dependency injection in .NET and how to resolve dependency?
- Ans.
Dependency injection in .NET is a design pattern where dependencies are injected into a class rather than the class creating them itself.
