LeetCode Problem 151: Reverse Words in a String | C# Step-By-Step Solution Explained

Here's my solution to the LeetCode Problem 151: Reverse Words in a String, implemented in C# using an intuitive List and Iteration Approach. 🚀 💡 Problem Overview: The objective of this problem is to reverse the order of words in a given string while ensuring that extra spaces are removed and words are separated by only a single space. This solution extracts the words from the string, stores them in a list, and combines them in reverse order to form the final string. ✅ What You'll Learn in This Video: How to efficiently extract words from a sentence while removing extra spaces. Using a List in C# to store and manipulate words. Reversing a list of words to construct the final output in an elegant way. 🔔 Code Highlights: Time Complexity: O(n), where n is the length of the string, as we traverse through the string only once and reverse the words in an additional linear pass. Space Complexity: O(n), as we use a list to store the extracted words. Core Insight: The solution focuses on trimming unnecessary spaces and using a list to store words, which are then concatenated in reverse order to form the reversed sentence. 💡 This problem is an excellent exercise for mastering string manipulations and handling whitespace, especially in the context of real-world scenarios like text formatting. 🎥 If you found value in this explanation, don’t forget to Like, Subscribe, and Share for more insightful LeetCode tutorials, coding strategies, and algorithm breakdowns! ✨ #LeetCode #ReverseWords #StringManipulation #CSharp #ProblemSolving #TextFormatting #CodingInterview #Algorithms
