Implement a data structure supporting the following operations: Inc(Key) - Inserts a new key with value 1. Or increments an existing key by 1. Key is guaranteed to be a non-empty string. Dec(Key) - If Key's value is 1, remove it from the data structu…

Implement a Trie Data Structure, and search() & insert() function: we need to implement both Class Trie and Class TrieNode Class Trie: import java.util.ArrayList; import java.util.List; public class Trie { private TrieNode root; /** * Constructor */…

For example we have an array of words: [car, done, try, cat, trie, do] What is the best data structure to store the data and easy for search? We can use Trie data structure, it is a tree, but not a binary tree. The reuslts of constructing a tree by u…

Source, git Heap is a data structure that can fundamentally change the performance of fairly common algorithms in Computer Science. The heap data structure is called a heap because it satisfies the heap property. The heap property states, that if P i…
In a tree, nodes have a single parent node and may have many children nodes. They never have more than one parent nor point to any siblings. The most common tree structure you see is a web page. The underlying structure is often called the "DOM tree&…
