Explanation of sorting techniques and implementation of bubble sort
Sorting techniques include bubble sort, selection sort, insertion sort, merge sort, quick sort, etc.
Bubble sort compares adjacent elements and swaps them if they are in the wrong order, repeating until the array is sorted.
Example: [5, 3, 8, 2, 1] -> [3, 5, 8, 2, 1] -> [3, 5, 2, 8, 1] -> [3, 5, 2, 1, 8] -> [3, 2, 5, 1, 8] -> [3, 2, 1, 5, 8] -> [2, 3, 1,
Binary search is a search algorithm that finds the position of a target value within a sorted array.
Divide the array into two halves and compare the target value with the middle element.
If the target value is less than the middle element, search the left half. If greater, search the right half.
Repeat the process until the target value is found or the subarray is empty.

Mixed conceptual questions from java8, Spring Boot and SQL and microservices
Singleton pattern ensures only one instance of a class is created and provides a global point of access to it.
Use lazy initialization to create the instance only when needed.
Use synchronized keyword to make the getInstance() method thread-safe.
Consider using double-checked locking for better performance.
Use enum to implement singleton pattern as it is inherently thread-safe.
Linked list is a data structure where each element points to the next element in the sequence.
Nodes contain data and a reference to the next node
Insertion and deletion can be done efficiently in a linked list
Traversal starts from the head node and follows the next pointers
