Prim's algorithm is a greedy algorithm used to find the minimum spanning tree for a connected, undirected graph.
Start with an arbitrary vertex and grow the tree by adding the shortest edge that connects the tree to a vertex not in the tree.
Repeat until all vertices are included in the tree.
Example: Given a graph with vertices A, B, C, D and edges with weights, find the minimum spanning tree using Prim's algorithm.

The question is asking for a variation of sorting an array containing 0s, 1s, and 2s.
Use a three-way partitioning algorithm to sort the array in a single pass.
Keep track of three pointers - low, mid, and high to partition the array.
Example: Input array = [0, 1, 2, 1, 0], Output array = [0, 0, 1, 1, 2]
A palindromic substring is a string that reads the same forwards and backwards.
Use dynamic programming to find the longest palindromic substring.
Start by considering each character as the center of a potential palindrome.
Expand outwards from each center to check for palindromic substrings.
Keep track of the longest palindrome found so far.
Example: Input 'babad', Output 'bab' or 'aba'.

Indexing in DBMS is a technique to improve the performance of queries by creating a data structure that allows for faster retrieval of data.
Indexes are created on columns in a database table to speed up the retrieval of rows that match a certain condition.
Types of indexes include clustered, non-clustered, unique, and composite indexes.
Examples of indexing techniques include B-tree, hash, and bitmap indexes.
Indexing can...
Check if two strings are anagrams by comparing the sorted characters in each string.
Sort the characters in both strings and compare if they are equal.
Ignore spaces and punctuation when comparing the strings.
Example: 'listen' and 'silent' are anagrams.
Example: 'hello' and 'world' are not anagrams.
Use a stack to simulate the recursive inorder traversal process
Create an empty stack to store nodes
Start with the root node and push it onto the stack
While the stack is not empty, keep traversing left and pushing nodes onto the stack
Once you reach a leaf node, pop it from the stack, print its value, and move to its right child
Repeat the process until all nodes have been visited
To make a class final, use the 'final' keyword in the class declaration.
Use the 'final' keyword before the 'class' keyword in the class declaration
A final class cannot be subclassed or extended
Final classes are often used for utility classes or classes that should not be modified
