LeetCode 58: Length of Last Word Solution

Hello dudes and dudettes!! 🚀 Day 19/150 — Solved LeetCode 58: Length of Last Word Today’s problem looked super simple at first… but taught me a great lesson about handling edge cases carefully 😄 🧠 What’s the Problem About? You’re given a string that contains words separated by spaces. Your task is to find the length of the last word. Sounds easy, right? Well… not always 👇 💡 The Catch The string might contain: Extra spaces at the beginning Extra spaces at the end Multiple spaces between words So it’s not just about “finding the last word” — it’s about finding the last valid word. 🔥 Example Input: " hello world " At first glance, it looks messy 😵 But the actual last word is: 👉 "world" 👉 Length = 5 🧠 The Thought Process Instead of trying to split everything immediately, I started thinking: Why not scan from the end? Because: The last word is always near the end We can skip spaces quickly Then just count characters until we hit a space ⚙️ Approach That Worked Ignore trailing spaces Start from the end of the string Count characters until a space appears That count is your answer Simple, efficient, and clean. 😎 Why This Problem Is Interesting It’s not about complexity — it’s about precision It shows how small edge cases can break simple logic It encourages thinking in reverse (which is surprisingly powerful) 💡 What I Learned Always consider edge cases like extra spaces Sometimes scanning backward is smarter than forward Even easy problems can sharpen your attention to detail 🎯 Key Takeaway “Simple problems aren’t always trivial — they test how carefully you think.” 🔥 Another step forward — improving not just coding skills, but problem-solving mindset. #LeetCode #Algorithms #ProblemSolving #CodingJourney #100DaysOfCode #Python #LearningInPublic
