Trie Interview Questions and Practice Problems

Trie is a tree-based data structure, which is used for efficient retrieval of a key in a large data-set of strings. Unlike a binary search tree, where node in the tree stores the key associated with that node, in trie node’s position in the tree defines the key with which it is associated and the key are only associated with the leaves. It is also known as prefix tree as all descendants of a node have a common prefix of the string associated with that node, and the root is associated with the empty string.
