Can't pass Platform Developer 1? You might be doing it wrong. After helping many people pass PD1 cert, I can confidently say this: Trying to rush PD1 without solid coding skills is a hustle. But don't get me wrong. → You'll learn something new. → PD1 is good for your market value. → You can pass PD1 with minimal coding skills. But if your goal is to understand the concepts behind 1. Focus on learning fundamentals 2. Learn Apex on a good level 3. Learn Tests in Apex 4. Learn Visualforce 5. Learn LWC And PD1 will flow naturally as a result. Power to you, my friend ❤️ Platform Developer 1 is worth doing. P.S. From how many tries did you pass PD1? (be honest)

You use databases every day, but do you know how they work internally? What does their architecture look like? As a software engineer, I've always wanted to explore the open-source code of various databases, and as a teacher, I've always wanted to teach this. Both are finally happening—In the first video of our 𝐅𝐫𝐞𝐞 𝐂𝐨𝐮𝐫𝐬𝐞, 𝐃𝐚𝐭𝐚𝐛𝐚𝐬𝐞𝐬 𝐢𝐧 𝐃𝐞𝐩𝐭𝐡 (available on my YouTube channel), we start by understanding the general architecture. In the next video, we will dive into BTrees and why so many databases use them. We’ll make “complicated” concepts super-simple, and you’ll feel cool and confident when debugging the open-source code with me. If you missed the first video, check out the link in the comments. P.S. - BTrees are part of which layer in this diagram? Let’s see how many of you can answer.

🚀 Day 45 of My 100-Day Coding Challenge: Simplify Path 🚀 Today's challenge was about working with Unix-style file paths and simplifying them to their canonical form. This problem highlighted the importance of understanding stack-based solutions for path manipulation. 🔍 Problem Overview: Given a Unix-style absolute file path, simplify it according to specific rules: Remove redundant slashes. Handle single (.) and double (..) periods representing current and parent directories. Construct the canonical path starting with / and avoid trailing slashes (except for the root directory). 💡 Example: Input: path = "/home/" Output: "/home" Explanation: The trailing slash is removed to provide a canonical path. #100DaysOfCode #StringManipulation #UnixPath #CodingChallenge

🚀 LeetCode Challenge: [🔥Day 303] 🔍 Problem Title: ❓Magic Squares In Grid 📝 Description: 🧐A 3 x 3 magic square is a 3 x 3 grid filled with distinct numbers from 1 to 9 such that each row, column, and both diagonals all have the same sum. Given a row x col grid of integers, how many 3 x 3 contiguous magic square subgrids are there? Note: while a magic square can only contain numbers from 1 to 9, grid may contain numbers up to 15.   Example 1: YInput: grid = [[4,3,8,4],[9,5,1,9],[2,7,6,2]] Output: 1 Explanation: The following subgrid is a 3 x 3 magic square: o while this one is not: u In total, there is only one magic square inside the given grid. Example 2: Input: grid = [[8]] Output: 0   Constraints: row == grid.length col == grid[i].length 1 <= row, col <= 10 0 <= grid[i][j] <= 15 🔗Link to Problem: https://lnkd.in/ddYkS4pU ✨ Why this Challenge is Worth Your Time: Sharpen your problem-solving skills.

Have you ever wondered what cache is and why it's so important in computer science? Caching is like a smart shortcut that saves time by keeping frequently used data handy. But how does this work in real-world scenarios? That's where the LRU (Least Recently Used) Cache comes in! In my latest video, I break down the concept of LRU Cache with a problem-solving approach that will challenge your thinking. 💡Patience Pays Off: Watching the video might take some time, and you might even think, "Should I just quit because it's a 1-hour video?" But remember, good things take time. Trust the process, because once you understand the solution, you'll learn something new and powerful!

🚀 LeetCode Challenge: 🔥Day 293 🔍 Problem Title: ❓Minimum Deletions to Make String Balanced 📝 Description: 🧐You are given a string s consisting only of characters 'a' and 'b'​​​​.You can delete any number of characters in s to make s balanced. s is balanced if there is no pair of indices (i,j) such that i < j and s[i] = 'b' and s[j]= 'a'. Return the minimum number of deletions needed to make s balanced.   Example 1: Input: s = "aababbab" Output: 2 Explanation: You can either: Delete the characters at 0-indexed positions 2 and 6 ("aababbab" -> "aaabbb"), or Delete the characters at 0-indexed positions 3 and 6 ("aababbab" -> "aabbbb"). Example 2: Input: s = "bbaaaaabb" Output: 2 Explanation: The only solution is to delete the first two characters.   Constraints: 1 <= s.length <= 105 s[i] is 'a' or 'b'​​. 🔗 Link to Problem: https://lnkd.in/dfgSAXsc ✨ Why this Challenge is Worth Your Time: Sharpen your problem-solving skills.
