👉 The tries fluid, also known as tries or trie data structures, is a versatile and efficient way to store and manipulate sets of strings. It is essentially a tree-like structure where each node represents a string, and each path from the root to a leaf corresponds to a unique string. This structure allows for fast prefix matching, insertion, and deletion operations, making it particularly useful for tasks like autocomplete suggestions, spell-checking, and IP routing. The tries fluid optimizes memory usage by sharing common prefixes among strings, ensuring that only unique characters are stored at each node. This makes it highly efficient for handling large datasets of strings with common prefixes.
