Are linked lists considered linear or non-linear data structures?
A linked list is considered both linear and non-linear data structure depending upon the situation. Based on data storage, it is considered a non-linear data structure. Based on the access strategy, it is considered a linear data structure.

The List is not required to be contiguously present in the main memory, if the contiguous space is not available, the nodes can be stored anywhere in the memory connected through the links.

- The size of a linked list can be incremented at runtime which is impossible in the case of the array.
- The List is not required to be contiguously present in the main memory, if the contiguous space is not available, the nodes can be stored anywhere in the memory connected through the links.
- The List is dynamically stored in the main memory and grows as per the program demand while the array is statically stored in the main memory, the size of which must be declared at compile time.
- The number of elements in the linked list is limited to the available memory space while the number of elements in the array is limited to the size of an array.

Define the queue data structure.
A queue can be defined as an ordered list that enables insert operations to be performed at one end called REAR and delete operations to be performed at another end called FRONT.

The following are some widely accepted principles of Agile testing:
- Provide Continuous Feedback: Agile testers not only test constantly but also share test results with end-users, gather feedback, and share it with developers to produce a more robust product.
- Deliver Value to Customer: The ultimate objective of any Agile tester is to generate the best possible product for end customers.
- Decrease Feedback Response Time: Testers work closely with the business team to reduce feedback response time
- Keep it Simple: Agile testers only perform necessary tests to maintain efficiency. They try to deliver a simple product with the best value and correct bugs within the same iteration.
- Practice Continuous Improvement: Agile testers make continuous improvements to the product.
- Respond to Change: Agile testers always respond to the feedback they get from customers to each user story of a product.
- Less Documentation: The testing team should follow a standard set of practices to reduce documentation and streamline the process.

Agile is an iterative and incremental approach to project management in software development. The clients and developers collaborate to work as requirements change throughout development.
With the Agile methodology, the software development team divides the project into smaller parts and works on them incrementally for quick client feedback with continual improvement. The team uses these backlogs to understand the final product and help the development process move along. This approach is popular and effective because it also involves the clients and their feedback, resulting in quick updates.

In non-agile development processes, backlog refinement is requirements management and analysis. Although it is structured very differently from the conventional requirements artifacts of the past, the backlog is the requirements spec. Since you’ll undoubtedly have to redo work that you spend time perfecting for more than a few sprints in the future, the PO is continuously working to keep the backlog ahead of the team without going too far into the future.
Scrum is made to facilitate the requirements’ ongoing evolution. The PO can refine without the assistance of the full team. They ought to incorporate stakeholders who know the requirements as well as team members who have experience in all pertinent fields.

The following are the five Scrum values:
Openness
Each Scrum team member must be honest about their development if they are to make significant advancements in short periods.
Courage
Scrum teams need to have the guts to be open, honest, and genuine with themselves and other stakeholders about any bottlenecks they encounter and the project’s development. The team’s members must also be courageous to seek assistance when necessary, experiment with novel methods, and respectfully disagree and publicly debate.
Focus
Every team member must focus on current work and understand how it affects the sprint goal. Scrum masters may restrict the number of tasks or priorities assigned to each team member to maintain engagement during sprints.
Respect
Respect in a Scrum team involves acknowledging that no one’s input is more valuable than another’s. Respect entails acknowledging your successes, having faith in your teammates, and respecting their opinions.
Commitment
Scrum teams must cooperate to accomplish a common goal. This entails having faith in one another to complete assignments and give their best effort. This can only happen if every team member is fully dedicated to the group and the project.
