Right Answer:
The purpose of feature engineering in data analysis is to create, modify, or select variables (features) that improve the performance of machine learning models by making the data more relevant and informative for the analysis.

Right Answer:
Data analysis is the process of inspecting, cleaning, and modeling data to discover useful information, draw conclusions, and support decision-making. It is important because it helps organizations make informed decisions, identify trends, improve efficiency, and solve problems based on data-driven insights.

Right Answer:
Regression analysis is a statistical method used to examine the relationship between one dependent variable and one or more independent variables. It is used to predict outcomes, identify trends, and understand the strength of relationships in data.

Right Answer:
Supervised learning uses labeled data to train models, meaning the output is known, while unsupervised learning uses unlabeled data, where the model tries to find patterns or groupings without predefined outcomes.

Right Answer:
Common types of linking errors include:

1. **Undefined References**: Occurs when a function or variable is declared but not defined. Resolve by ensuring all referenced functions/variables are defined and linked correctly.

2. **Multiple Definitions**: Happens when the same function or variable is defined in multiple files. Resolve by using `extern` for declarations in header files and ensuring only one definition exists.

3. **Library Not Found**: Occurs when the linker cannot find a specified library. Resolve by checking the library path and ensuring the library is correctly installed and linked.

4. **Incompatible Object Files**: Happens when object files are compiled with different settings or incompatible versions. Resolve by recompiling all object files with consistent settings.

5. **Symbol Conflicts**: Occurs when two or more symbols have the same name. Resolve by renaming conflicting symbols or using namespaces.

6. **Incorrect Link Order**: Happens when libraries are linked in the wrong order, causing dependencies to be unresolved

Right Answer:
To use REST APIs in Alfresco for external integrations:

1. **Authentication:** Authenticate using credentials or a ticket.
2. **Construct URL:** Build the API endpoint URL (e.g., `/alfresco/api/-default-/public/alfresco/versions/1/nodes/{nodeId}`).
3. **HTTP Method:** Use appropriate HTTP methods (GET, POST, PUT, DELETE).
4. **Data Format:** Send/receive data in JSON format.
5. **Error Handling:** Implement error handling based on HTTP status codes.

Right Answer:
The main compiler optimization levels are:

1. **O0**: No optimization; the compiler generates the simplest code for debugging.
2. **O1**: Basic optimizations that improve performance without significantly increasing compilation time.
3. **O2**: More aggressive optimizations that enhance performance while still keeping compilation time reasonable.
4. **O3**: Maximum optimizations that may increase compilation time and can include aggressive techniques like loop unrolling.
5. **Os**: Optimizations focused on reducing code size.
6. **Ofast**: Disregards strict standards compliance for maximum performance, enabling all optimizations including those that may not be safe.

Each level balances between compilation time, execution speed, and code size.

Right Answer:

Right Answer:
You can test the performance of a website without using an automation tool by manually checking the following:

1. **Load Time**: Use a stopwatch to measure how long it takes for the website to fully load in different browsers and devices.
2. **Page Size**: Check the size of the web pages using browser developer tools to see how much data is being loaded.
3. **Network Speed**: Test the website on different internet connections (e.g., 3G, 4G, Wi-Fi) to see how performance varies.
4. **User Experience**: Navigate through the site to assess responsiveness and ease of use.
5. **Browser Developer Tools**: Use built-in tools (like Chrome DevTools) to analyze network requests, identify bottlenecks, and monitor resource loading times.
6. **Stress Testing**: Simulate multiple users accessing the site simultaneously by asking friends or colleagues to access it at the same time and observe any slowdowns or crashes.
