🚀 Today I focused on strengthening my Python fundamentals by practicing String-based problems — one of the most important topics in programming. Here’s what I worked on today 👇 🔹 Reversing a string 🔹 Checking for Palindrome 🔹 Counting character frequency 🔹 Extracting first & last characters 🔹 Finding the longest word in a list 🔹 Counting word occurrences in a sentence 🔹 Converting input to upper & lower case 🔹 Removing duplicate words 🔹 Checking if two strings are Anagrams 💡 These problems helped me improve my understanding of: ✔️ String manipulation ✔️ Dictionaries & data structures ✔️ Problem-solving approach ✔️ Writing clean and efficient code Every small step like this builds a stronger foundation in programming. Consistency is the key! 🔥 📌 Next Goal: Moving towards more advanced data structures and real-world problem solving. #Python #CodingJourney #100DaysOfCode #Programming #Developer #Learning #ProblemSolving #TechSkills #BTech
