If you are an aspiring software engineer or a coding enthusiast, chances are you have come across the term “trie” or “prefix tree”. Tries are efficient data structures used for storing and searching strings. They have numerous applications in fields like natural language processing and information retrieval. In this article, we will explore a comprehensive guide to implementing trie and solving 75 LeetCode questions blindfolded.
Implementing a trie can be a daunting task, especially if you are new to data structures and algorithms. However, with the right guidance and practice, you can master this powerful data structure. Hackernoon has provided an in-depth tutorial on how to implement trie, along with blind 75 LeetCode questions to test your understanding. This article aims to highlight the importance of trie and provide a list of the questions covered in the Hackernoon tutorial.
Before we delve into the questions, let’s briefly understand what a trie is. A trie, also known as a prefix tree, is an ordered tree data structure that stores a set of strings. Each node in the trie represents a character, and the edges represent the next character in the string. Tries are particularly useful when it comes to searching for words or prefixes efficiently.
