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 palindromes of odd and even lengths.
Remove duplicates from a 1D array of strings in place
Iterate through the array and use a HashSet to keep track of unique elements
Replace duplicates with null or an empty string to remove them in place
Search for the minimum element in a rotated sorted array with duplicate elements.
Use binary search to find the minimum element in the rotated sorted array.
Handle the case where duplicate elements are present by adjusting the search conditions.
Consider cases where the array is not rotated or contains only one element.
A singleton class is a class that can only have one instance created throughout the application.
Declare a private static instance variable of the class
Create a private constructor to prevent external instantiation
Provide a public static method to access the instance

Indexing in databases is a way to optimize search queries by creating a data structure that allows for faster retrieval of data.
Indexing creates a data structure (like B-trees or hash tables) that maps keys to the locations of corresponding data entries.
When a query is made, the database engine uses the index to quickly locate the relevant data entries instead of scanning the entire database.
Indexes can be created on o...
