LeetCode 75 C++ | Step-by-Step Solutions (LAN Academy) - 151 Reverse Words in a String (C++) | Split + Reverse | LeetCode 75 #06

sa pastrezi inrarea si iesirea Do you want to master LeetCode problems and think like a real interviewer? In this video, we solve LeetCode 151 – Reverse Words in a String, a classic string-cleanup + ordering problem in C++. Most people get stuck on edge cases (multiple spaces, leading/trailing spaces). The clean interview-ready approach is: trim + normalize spaces, then reverse word order in a structured way (O(n), robust, no messy special-casing). What you'll learn: How to remove extra spaces efficiently (normalize to single spaces) How to extract words cleanly and rebuild the string in reversed order How to write a clean O(n) C++ solution with solid space handling Edge cases interviewers always test: " hello world " → "world hello" Core idea (quick intuition): We only care about words, not the exact spacing. So we parse words, then output them in reverse order with exactly one space between them.
