Q1. What is an application of AVL Tree in database
Ans. 
AVL Trees are used in databases to efficiently store and retrieve data in a balanced manner.
• AVL Trees help maintain balance in database indexes, ensuring efficient search and retrieval operations.

• They are commonly used in database management systems like MySQL and Oracle.

• AVL Trees are particularly useful for range queries and ordered traversal of data in databases.

• They provide faster search times compared to unbalanced...read more

Q2. How topological sorting works
Ans. 
Topological sorting is a linear ordering of vertices in a directed acyclic graph where for every directed edge uv, vertex u comes before vertex v.
• Topological sorting is used in scheduling tasks with dependencies, such as in project management.

• It can be implemented using depth-first search algorithm.

• Example: In a course prerequisite graph, topological sorting can help determine the order in which courses should be taken

Q3. What is operator overloading
Ans. 
Operator overloading is the ability to define new meanings for operators in a programming language.
• Allows operators to be used with user-defined data types

• Can redefine the behavior of operators like +, -, *, /, etc.

• Example: Overloading the + operator to concatenate strings

Q4. Difference in linear and non linear data structure
Ans. 
Linear data structures store data in a sequential manner, while non-linear data structures allow for more complex relationships between data points.
• Linear data structures include arrays, linked lists, queues, and stacks.

• Non-linear data structures include trees, graphs, and heaps.

• Linear data structures have a simple, one-dimensional layout, while non-linear data structures can have multiple dimensions and complex relati

Q5. Which provides feasible solution for puzzle problem backtracking or branch and bound
Ans. 
Branch and bound provides a feasible solution for puzzle problems compared to backtracking.
• Branch and bound is more efficient in finding optimal solutions by pruning branches that cannot lead to a better solution.

• Backtracking explores all possible solutions before finding the optimal one, which can be inefficient for large puzzle problems.

• For example, in the traveling salesman problem, branch and bound can be used to f...read more

Q1. Greedy and DP which divides Data and which divides the domain?
Ans. 
Greedy algorithm divides the domain, while Dynamic Programming divides the data.
• Greedy algorithm focuses on making the best choice at each step without considering the overall solution, dividing the domain into subproblems.

• Dynamic Programming breaks down a problem into smaller subproblems and solves each subproblem only once, dividing the data into overlapping subproblems.

• Example: In the Knapsack problem, Greedy algori...read more

Q2. If the size of an input image is 1000 x 1000 and filter of 3x3 applied with stride 1, what will be the dimensions of output image?
Ans. 
The dimensions of the output image will be 998 x 998.
• Output image dimensions = (input image dimensions - filter dimensions + 1) / stride

• In this case, (1000 - 3 + 1) / 1 = 998

• Therefore, the output image will be 998 x 998
