Bubble Sort is the simplest sorting algorithm that works by repeatedly swapping the adjacent elements if they are in the wrong order.

Pseudocode:

bubbleSort(arr[], n) 
{ 
	for (i = 0 to i < n-1) do :
	// Last i elements are already in place 
		for (j = 0 to j < n-i-1) do : 
			if (arr[j] is greater than arr[j+1]) 
				swap(arr[j], arr[j+1])
}

The Collection in Java is a framework that provides an architecture to store and manipulate the group of objects. Java Collections can achieve all the operations that you perform on a data such as searching, sorting, insertion, manipulation, and deletion. Java Collection means a single unit of objects. Java Collection framework provides many interfaces (Set, List, Queue, Deque) and classes (ArrayList , Vector, LinkedList , PriorityQueue , HashSet, LinkedHashSet, TreeSet).

The List interface in Java provides a way to store the ordered collection. It is a child interface of Collection. It is an ordered collection of objects in which duplicate values can be stored. Since List preserves the insertion order, it allows positional access and insertion of elements.

Multiple inheritance is not supported by Java using classes, handling the complexity that causes due to multiple inheritances is very complex. It creates problems during various operations like casting, constructor chaining, etc, and the above all reason is that there are very few scenarios on which we actually need multiple inheritances, so better to omit it for keeping things simple and straightforward.

During recursion, there may exist a case where same sub-problems are solved multiple times.
But Dynamic programming is a technique where you store the result of previous calculation to avoid calculating the same once again. DP is basically a memorization technique which uses a table to store the results of sub-problem so that if same sub-problem is encountered again in future, it could directly return the result instead of re-calculating it.

Tip 1 : Be sure to do your homework on the organization and its culture before the interview.

Tip 2 : Employers want to understand how you use your time and energy to stay productive and efficient. Be sure to emphasize that you adhere to deadlines and take them seriously.
 

Tip 3 : Talk about a relevant incident that made you keen on the profession you are pursuing and follow up by discussing your education.
