2 DSA questions and some MCQ on Java and Spring
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

Hoisting is a JavaScript mechanism where variable and function declarations are moved to the top of their containing scope.
Variable and function declarations are hoisted to the top of their scope during the compilation phase.
Only the declarations are hoisted, not the initializations.
Function declarations take precedence over variable declarations when hoisted.

String arrays are immutable because they cannot be changed once created.
Strings in an array cannot be modified individually
Any changes to a string array result in a new array being created
Immutable arrays ensure data integrity and prevent unintended side effects
To create a custom immutable class, use final keyword for class, private final fields, and no setter methods.
Use the final keyword for the class to prevent inheritance
Declare all fields as private and final to prevent modification
Do not provide setter methods for the fields to maintain immutability
Provide getter methods to access the fields
