Question 1

What are the advantages of using a trie?

Accepted Answer

A trie is highly efficient for prefix-based searches, such as autocomplete. It can also be used for searching for words in a dictionary and for IP routing.

Question 2

What is the time complexity of insertion and search in a trie?

Accepted Answer

The time complexity of insertion and search in a trie is O(L), where L is the length of the word. This is because you traverse the trie from the root to the node corresponding to the last character of the word.
