Which Data Structure Gives Fastest Retrieval Operation?

Trie. Trie, which is also known as “Prefix Trees”, is a tree-like data structure which proves to be quite efficient for solving problems related to strings. It provides fast retrieval, and is mostly used for searching words in a dictionary, providing auto suggestions in a search engine, and even for IP routing.

Which is the fastest data structure for searching an element?

The best data structure for faster searching of string is TRIE. Tries are an extremely special and useful data-structure that are based on the prefix of a string. They are used to represent the “Retrieval” of data. A Trie is a special data structure used to store strings that can be visualized like a graph.

Which is faster vector or linked list?

For example, taking a bunch of random integers and inserting them in sorted order into a vector or a linked list -- the vector will always be faster, regardless of the number of items total, due to cache misses when searching for the insertion point in the linked list.
