Memorial University of Newfoundland Postdoctoral Researcher Interview Questions and Answers

To debug a particular program without affecting others, use breakpoints and step through the code.

• Set a breakpoint in the program you want to debug

• Step through the code using a debugger to identify the issue

• Use logging statements to track the flow of the program

• Check the call stack to see which functions are being called

• Use conditional breakpoints to stop the program at specific points

If and Switch Case statements are used for conditional branching in programming.

• If statements are used for simple conditional branching.

• Switch Case statements are used for multiple conditional branching.

• If statements are more flexible than Switch Case statements.

• Switch Case statements are more efficient than If statements for large number of conditions.

• If statements can be nested, but Switch Case statements cannot.

Yes, algorithms and pseudocodes are still important in IT Services.

• Algorithms are used in various fields of IT such as machine learning, data analysis, and cryptography.

• Pseudocodes are used to plan and design algorithms before coding them.

• Understanding algorithms and pseudocodes is essential for software engineers to write efficient and optimized code.

• Examples of algorithms include sorting algorithms, search algorithms...read more

Yes, I am comfortable using both CLIs and IDEs for my daily tasks.

• I have experience using various CLIs such as Git Bash, Windows Command Prompt, and Terminal on macOS.

• I am proficient in using IDEs such as Visual Studio Code, Eclipse, and IntelliJ IDEA.

• I understand the benefits and drawbacks of both CLIs and IDEs and can choose the appropriate tool for the task at hand.

OOPs concepts are the fundamental principles of object-oriented programming.

• Encapsulation - binding data and functions that manipulate the data

• Inheritance - creating new classes from existing ones

• Polymorphism - ability of objects to take on many forms

• Abstraction - hiding implementation details and showing only functionality

Storage classes in C define the scope and lifetime of variables.

• There are four storage classes in C: auto, register, static, and extern.

• Auto variables are local to a block and have automatic storage duration.

• Register variables are stored in CPU registers for faster access.

• Static variables have a lifetime throughout the program and are initialized only once.

• Extern variables are declared outside any function and can be a...read more

Linked list is a linear data structure. DFS and BFS are graph traversal algorithms.

• Linked list is a collection of nodes where each node points to the next node.

• DFS (Depth First Search) is a traversal algorithm that explores as far as possible along each branch before backtracking.

• BFS (Breadth First Search) is a traversal algorithm that explores all the vertices of a graph in breadth-first order.

• Example of linked list: ...read more

Optimize O(n2) program to O(log n)

• Use binary search instead of linear search

• Divide and conquer approach can be used

• Implement efficient data structures like heap, AVL tree, etc.

• Reduce unnecessary iterations and comparisons

• Use memoization to avoid redundant calculations
