Bounteous x Accolite Software Engineer Interview Questions and Answers for Freshers

Use tree traversal to find the minimum number in a tree structure.

• Start at the root node and compare it with its children to find the minimum value.

• Use depth-first search or breadth-first search to traverse the tree.

• Keep track of the minimum value found so far as you traverse the tree.

• Consider implementing a recursive function to traverse the tree efficiently.

OOP (Object-Oriented Programming) is a programming paradigm based on objects and classes, promoting code reusability and modularity.

• Encapsulation: Bundling data and methods that operate on the data within one unit (e.g., a class).

• Inheritance: Mechanism to create a new class from an existing class, inheriting attributes and methods (e.g., a 'Dog' class inheriting from an 'Animal' class).

• Polymorphism: Ability to pre...read more

The question requires writing code, likely involving algorithms or data structures.

• Understand the problem requirements clearly before coding.

• Break down the problem into smaller, manageable parts.

• Choose appropriate data structures (e.g., arrays, lists, trees).

• Write pseudocode to outline your logic before actual coding.

• Test your code with various inputs to ensure correctness.

Reversing a linked list involves changing the direction of the pointers between nodes.

• Iterate through the list while maintaining three pointers: previous, current, and next.

• Set the current node's next pointer to the previous node.

• Move the previous and current pointers one step forward.

• Repeat until the end of the list is reached.

• Example: For list 1 -> 2 -> 3, the reversed list will be 3 -> 2 -> 1.

Finally is a block of code that executes after try-catch block. It will not execute if System.exit() is called.

• Finally block is used to execute a block of code after try-catch block

• It will execute even if an exception is thrown

• Finally block will not execute if the JVM exits before the block is executed

• System.exit() terminates the JVM and finally block will not execute

Implement a function to perform topological sorting on a directed acyclic graph (DAG) and return any valid ordering.

• Create a graph representation using adjacency list or matrix

• Perform depth-first search (DFS) to find the topological ordering

• Use a stack to keep track of the ordering

• Return the ordering as an array of integers
