Climbing Stairs with Dynamic Programming

🗓 Day 87 / 100 – #100DaysOfLeetCode 📌 Problem 44: Wildcard Matching Today’s problem was a classic dynamic programming challenge involving string pattern matching. The task was to determine whether a string matches a pattern containing: ? → matches any single character * → matches any sequence of characters (including empty) 🧠 My Approach: Used Dynamic Programming where: dp[i][j] represents whether the first i characters of the string match the first j characters of the pattern Handled base cases carefully: Empty string vs pattern Patterns starting with * Transition rules: If characters match or pattern has ? → inherit diagonal state If pattern has * → either: match zero characters or match one/more characters Final answer comes from dp[n][m]. This approach ensures all wildcard possibilities are handled correctly. 💡 Key Learning: This problem reinforced: ✔ thinking in terms of states and transitions ✔ handling multiple matching paths with DP ✔ importance of correct base-case initialization Wildcard matching problems are great practice for mastering string DP patterns.

🚀 Day 13 | Functions – Code Reusability in C Language Today I learned how functions enable code reusability, one of the most important concepts in programming. 🔹 Write code once, use it multiple times 🔹 Avoids repetition and reduces errors 🔹 Makes programs clean, modular, and readable 🔹 Easy to debug, test, and maintain 💡 Functions turn long programs into simple, manageable blocks. 📌 Reusable code = Smart programming. #30DaysOfC #CProgramming #Functions #CodeReusability #ProgrammingBasics #CLanguage #CodingJourney #Day13

PROJECT - 1: 📘 From Learning to Building – "Address Book" in C As part of strengthening my fundamentals in C programming, I built an Address Book application with complete CRUD operations and file storage. This project helped me gain hands-on experience with: 🔹 Structures & pointers 🔹 File I/O operations 🔹 Logic building & debugging 🔗 Source Code (GitHub): 👉 https://lnkd.in/gj22GuFu 🎬 Code & output demo attached below. #emertxe #LearningByDoing #CProgramming #StudentDeveloper #GitHubProjects

📘 CAP 281 – Exploring Classes & Objects in C++ Today’s session was focused on understanding the fundamental concept of Classes and Objects, which form the backbone of Object-Oriented Programming (OOP). I learned how: ✔ Classes act as blueprints for creating objects ✔ Objects represent real-world entities ✔ Data members and member functions work together ✔ Encapsulation improves code structure and security Strengthening my OOP concepts step by step! 🚀 #CAP281 #Cpp #ObjectOrientedProgramming #ProgrammingJourney #BBAHonors #Learning

Conditional statements help make decisions in code. If condition true → execute Else → another path Programming is all about logic 🔥 #PHPCoding #ConditionalLogic #BackendDev

I've been writing a series on Functional Programming Through Elixir over at my   blog, and I'd love to hear your thoughts.  The series breaks down core FP concepts like immutability and first-class  functions by showing how they work in practice with Elixir.  Whether you're coming from an OOP background or deepening your functional  programming knowledge, I'm aiming to make these concepts concrete and  accessible.  Check it out at joser.ca  Would especially appreciate feedback on:  • What's landing well vs. what needs clarity  • Topics you'd like to see covered  • Any Elixir patterns or FP concepts you've struggled with

One of the best habits I’m currently building is writing pseudocode before writing real code. It forces me to slow down, think clearly, and design the logic first instead of jumping straight into syntax and getting stuck. If you’re new to programming, pseudocode is one of the simplest tools to reduce overwhelm and build real problem-solving skills. Clear thinking first. Clean code later. #OctoPrep #PythonDeveloper #DataScience #DataAnalysis

Built a C program to find the largest among three numbers 💻 Used stdio.h for input and output functions. Took user input using scanf(). Applied if-else if-else conditional statements. Used logical operators for comparison. Improved understanding of decision-making in C. Practiced clean syntax and structured coding. Strengthening core programming fundamentals step by step 🚀 Small logic programs help build strong problem-solving skills 🔥 Consistency is the key to mastering programming 💡 #CLanguage #Programming #CodingJourney #LearnToCode #CProgramming #StudentDeveloper #LogicBuilding #TechSkills #ComputerScience #VSCode
