Day 49: Coding Challenges Today, we tackled two challenging coding problems: one about finding the minimum absolute difference in a binary search tree and another about finding the single element in a sorted array. Problem Links:- 530. Minimum Absolute Difference in BST:- https://lnkd.in/eZqVMX_j 540. Single Element in a Sorted Array:- https://lnkd.in/enrpA9km Github:- https://lnkd.in/gjKwWR9k #100DaysOfCode #LeetCode #C++ #codingchallenge #day49 #trees #arrays #algorithms #datastructures #softwareengineer #tech #learning #growth

🚀 **Day 2 of #100DaysOfCode** 🚀 Super excited to share that I’ve completed **5 videos** of web development with **Code with Harry**, and today I dove into **JavaScript**! 🎯 It’s only day 2, but I’m already getting a feel for the power of JavaScript in making web pages interactive and dynamic. 💻 🌐 **Key Takeaways from Day 2**: - Got introduced to JavaScript basics and how it enhances websites beyond just HTML and CSS. - Learned about variables, data types, and the building blocks of JavaScript syntax. - Explored how JavaScript can be integrated into HTML to make interactive pages. - Wrote my first few functions, and I’m excited to see how I can use them to build cool web features! It’s amazing how adding just a little bit of JavaScript can bring a website to life. Every line of code feels like I’m unlocking new capabilities, and I’m eager to push further into learning how JavaScript can build real-world applications. 🔑 ⚡ **Why I’m Doing This**: Learning JavaScript is my step toward mastering full-stack development, and I’m committed to growing my skill set every day. This challenge is not just about learning—it’s about building, experimenting, and evolving with each new concept. 🌱 Onward to more coding, more projects, and more growth! 💡 #WebDevelopment #JavaScript #CodeWithHarry #100DaysOfCode #TechJourney #CodingChallenge #Programming #FrontEndDevelopment #LearningToCode

We talk about making source code readable and it turns out that this isn’t just stylistic interpretation; there is actual research into this topic. As we read through the code, what we’re scanning for are chunks and beacons. Chunks and beacons are similar in that they’re both code fragments, yet they’re used differently. “Chunks are described as code fragments in programs. Available literature shows Chunks to be used during the bottom-up approach of software comprehension. Chunks vary in size. Several Chunks can be combined into larger Chunks.” A looping structure could be a chunk, contained inside a method which is also a chunk, contained inside a class which is also a chunk. You’ve probably heard that our working memory can retain 7±2 (5-9) chunks of information at any one time. Our ability to chunk the source code allows us to retain more of the concepts in working memory at once. Experts are able to chunk more effectively than novices based on patterns that they’ve become familiar with. Even novices can benefit from structural chunking, however. “Beacons are code fragments that help developers comprehend programs. It has been shown that expert programmers pay more attention to Beacons than novices.” Beacons are often used to confirm hypotheses about the code. We start with a general hypothesis about what the code does, from documentation or conversation or perhaps naming. We then look to these beacons to confirm our understanding of this. Do we find the things that our hypothesis would expect us to find? If looking at a specific part of the code confirmed something you were thinking, that was a beacon. Beacons make it easier to chunk the code as they draw our attention. When reading through the code, an expert will recall the beacons far more easily than the non-beacons. Novices and intermediates will recall the non-beacons better, presumably because they were scanning line by line. When programmers know that specific design patterns are present in the code then those patterns become useful beacons. These don’t have to be named patterns that we would find in a catalog; they could be a swap operation in a sorting algorithm. Names in the code are important beacons. Ensuring that we have good variable names, will allow an expert to scan the code more effectively. For a version of this post that has links to research, see the first comment.

Hey everyone, I'm excited to share a new Python tool I've developed! 🚀 Introducing ftp_enum - a handy script for assessing permissions on FTP servers. With features like recursive scanning and directory printing, it makes FTP assessments a breeze. Check it out on GitHub and let me know what you think! #Python #FTP #OpenSource #GitHub 💻🔒 https://lnkd.in/dDW4dg-i
