Trie - Insert and Search

Trie is an efficient information retrieval data structure. Using Trie, search complexities can be brought to optimal limit (key length). If we store keys in a binary search tree, a well balanced BST will need time proportional to M * log N, where M is the maximum string length and N is the number of keys in the tree. Using Trie, we can search the key in O(M) time. However, the penalty is on Trie storage requirements (Please refer to Applications of Trie for more details) Trie - Insert and Search: https://www.geeksforgeeks.org/trie-insert-and-search/
