Substring Search in Strings with Python

Day 44 – Replacing a Substring in a String: Today’s task focused on replacing a specific substring within a given string using a clean and structured approach. This exercise strengthened understanding of string functions, user input handling, and text transformation, which are commonly used in data cleaning and text-processing tasks.

feb-23-26 LeetCode 1461 – Check If a String Contains All Binary Codes of Size K Solved today’s Daily Question! ✅ The problem asks to determine whether a binary string s contains all possible binary codes of length k as substrings. 🧠 Complexity: Time: O(n) Space: O(2^k) Simple logic + efficient implementation using hashing 🔥 #LeetCode #DailyCoding #Python #ProblemSolving #DataStructures #SlidingWindow #CodingJourney

Day 5 | Problem-Solving Practice Today was more of a revision and consolidation day. Reviewed and implemented several basic logic problems (conditionals and loops) as part of a 100-problem practice set. Even small problems help reinforce fundamentals and consistency. All solutions have been added to my GitHub repository for tracking progress. GitHub: https://lnkd.in/g35tV9Gj #ProblemSolving #Python #LearningInPublic

Day 58 – Removing Common Elements from Lists Day 58 focused on removing common elements between two lists using set operations. This exercise enhanced understanding of list manipulation, type conversion, and efficient comparison techniques in Python, along with handling dynamic user inputs for practical implementation.

LeetCode | Longest Common Prefix 🔤 🔹 Approach: Sorting + Compare first & last strings 🔹 Key idea: Common prefix must match between smallest and largest 🔹 Time Complexity: O(n log n + m) 🔹 Space Complexity: O(1) Daily DSA practice to improve problem-solving skills 🚀 After sorting, the common prefix of the first and last string gives the answer #LeetCode #DSA #Strings #Python #CodingJourney #LearningInPublic

Day 49 of Python with DSA 🚀 Today’s problem helped me deeply understand how linked lists differ from arrays. When asked to splice nodes, the goal is not to create new data — it’s to manipulate pointers and reuse existing memory. The more I practice, the more I improve at writing efficient, interview-ready solutions. Discipline + consistency = growth 💪 #Day49 #Python #DSA #LinkedList #ProblemSolving #SDE#CodingJourney

Day 64 – Counting Lines in a File using Python: Day 64 focused on counting the number of lines in a file using Python. I practiced reading file contents, using readlines() to store lines in a list, and calculating the total using len(). This exercise strengthened my understanding of file reading techniques, list handling, and efficient resource management using both the traditional method and the with statement.

Day 52 – Tuple Basics and Adding Elements: Day 52 focused on Python tuple fundamentals, including accessing elements, finding length, and understanding immutability. The task demonstrated how new elements can be added by creating a new tuple using concatenation. This exercise strengthened knowledge of tuple operations and reinforced core concepts of Python data structures.
