Data Structures and Algorithms The Complete Masterclass - Why Are Tries Important?

The video tutorial discusses the importance and advantages of using tries as a data structure, particularly focusing on their complexity and efficiency in handling word-based operations. Tries are beneficial for operations like searching, inserting, and deleting words, with a complexity of O(K), where K is the length of the word. They are also advantageous for prefix-based searches, allowing easy retrieval of words starting with a specific prefix. However, tries have a significant memory disadvantage, especially with small datasets, as they require substantial memory for each node. The tutorial concludes by highlighting the balance between the benefits and drawbacks of using tries.
