Diameter of a Binary Tree
- To find the diameter of a binary tree, we need to calculate the longest path between two leaf nodes.
- The diameter can pass through the root or not. If it does, the formula is (left_height + right_height + 1).
- If the diameter doesn't pass through the root, we use the formula max(left_diameter, right_diameter).
- The function for finding the diameter calculates the heights and diameters of the left and right subtrees.

How to Replace a String in Python
- Replacing strings in Python is a fundamental skill. You can use the .replace() method for straightforward replacements, while re.sub() allows for more advanced pattern matching and replacement.
- You can replace parts of a string by chaining .replace() calls or using regex patterns with re.sub().
- You replace a letter in a string by specifying it as the first argument in .replace().
- You remove part of a string by replacing it with an empty string using .replace() or re.sub().
- You replace all occurrences of substrings in a string by using .replace().
- In this tutorial, you’ll work with a chat transcript to remove or replace sensitive information and unwanted words with emojis. To achieve this, you’ll use both direct replacement methods and more advanced regular expressions.
- You’ll be playing the role of a developer for a company that provides technical support through a one-to-one text chat. You’re tasked with creating a script that’ll sanitize the chat, removing any personal data and replacing any swear words with emojis.
- The first thing you’ll want to do is to take care of any swear words.
- As you can see, you can chain .replace() onto any string and provide the method with two arguments. The first is the string that you want to replace, and the second is the replacement.
- But there’s another swear word that’s not getting replaced because in Python, the string needs to match exactly.

A Brief History of Python’s Error Messages
- Python's error messages have undergone significant changes, going from frustrating and confusing, to clear, helpful and intuitive.
- From Python 3.6 to Python 3.13, the error messages have become more user-friendly. Python's creator had strict guidelines for the development of Python’s error handling, known under the umbrella term exceptions.
- As of Python 3.13.0, there are 37 different error types and 11 warnings types that help inform users about potential bugs or incompatibilities within their code. The exception hierarchy has changed a lot since the birth of Python.
- Python 2.0 introduced the basic hierarchy of errors, making it so no error would ever pass undefined. Version 2.1 was the update to add warning classes for messages to the user that don’t kill the program.
- Version 3.10 was the first update to make considerable improvements in error message reporting of errors. For 3.11, more improvements were made to the error locations in tracebacks.
- The Python development team has made decisive efforts to improve error reporting to make the language even more user-friendly, intuitive and easy to use.
- From data scraped from the ‘What’s New in Python’ update logs, there is a sudden increase starting with Python 3.10 compared to the rest of Python 3 updates.
- The main question that arises is why there is deliberate effort to improve error messaging now. Future improvements to Python’s error messages past 3.14 are yet to be determined.
- Python error messages have come a long way and will continue to evolve in the best interests of developers and users alike.
- The Python community can look forward to even easier debugging with future releases and significant improvements in error reporting.

Height or Max depth if a BTree
- The height of a binary tree is calculated by finding the number of edges on the longest path from the root to a leaf node.
- Recursion can be used to calculate the height of a binary tree.
- The recursion function calculates the left height and right height of each node recursively.
- The maximum of the left and right heights, plus 1, gives the height of the binary tree.

Test Scenarios vs. Test Cases: Understanding the Differences
- Test scenarios are high-level descriptions of what to test, focusing on user journeys and real-world interactions with the system.
- Test cases are detailed, step-by-step instructions that guide testers through specific actions to verify expected outcomes.
- Test scenarios are ideal for exploratory testing, high-level planning, and situations where detailed documentation isn’t feasible.
- Test cases are best suited for detailed, repeatable testing, especially in highly regulated or complex systems.
- To maximize the effectiveness of test scenarios and test cases, it’s essential to follow industry best practices.
- The right tools and techniques can streamline the management of test scenarios and test cases, ensuring efficiency and consistency.
- Test scenarios and test cases are both indispensable tools in the tester’s toolkit, each serving unique and complementary roles.
- By understanding their differences and use cases, teams can build a testing strategy that is both efficient and effective.
- When used together, test scenarios and test cases ensure comprehensive test coverage, aligning technical details with real-world user experiences.
- Striking the right balance between these two approaches is key to delivering high-quality software.

Use Chrome's Prompt API to generate a trip planner in Angular
- The author of this article describes how to build a trip planner application locally using Chrome’s Built-In Prompt API and Angular.
- The article explains that the Angular application calls the Prompt API to create a language model and submit queries to Gemini Nano to provide details to the user such as applying for a travel visa, clothes to pack, and attractions to visit each day.
- The article explains that using Chrome’s built-in AI has zero cost since the application uses the local models in Chrome Canary.
- The article provides a step-by-step guide on installing dependencies, scaffolding an Angular application, and bootstraping the language model.
- The article explains that a validation logic is implemented to ensure that the Prompt API is available before displaying the user interface so users can enter texts.
- The article explains that the PromptResponseComponent displays a text area where users can enter a query. This query is submitted to the internal Gemini Nano which generates a text answer.
- The article defines a service layer over the Prompt API. The SystemPromptService service encapsulates the logic of the Prompt API.
- The article explains that software engineers can create Web AI applications without setting up a backend server or accumulating the costs of LLM on the cloud.
- The article provides a GitHub Repo and a demo for readers to learn more about the topic.
