1. Duplicate Encoder

1.1. Description

The goal of this exercise is to convert a string to a new string where each character in the new string is:

• “(“ if that character appears only once in the original string.
• “)” if that character appears more than once in the original string.
• Ignore capitalization when determining if a character is a duplicate.

1. Methodology

1.1. The Methodology Chapter

• The Methodology chapter of your final report can be seen as ‘taking the front off the machine’.
• It lets readers understand the workings of your research project, so that someone could repeat it.
• You must share and explain why you chose to conduct your research that way.

1.2. The structure of Methodology Chapter

• Introduction
• Research Approach
• Research Methods
• Ethical Considerations
• Limitations

1. Project issues

A project issue is an event or condition that has negative consequences for a project. The term implies a situation that is recoverable or that can be mitigated in some way.

1. Data Collection

1.1. Main concept

• credibility: the quality of being trusted and believed in (results are not made up, and its methods and results can be trusted)
• reliability: the extent to which findings are consistent; results are obtainable again under similar condition​s (same data would have been collected each time)
• validity: the extent to which a test measures or predicts what it is supposed to (the appropriateness/meaningfulness/usefulness of findings​)
• generalisability: whether findings are applicable to other research settings or organisations​
• trustworthiness: if research has credibility, transferability, dependability and confirmability
• authenticity: if research represents different viewpoints, helps improve the social setting and the understanding of others, and if it empowers members to engage in action

1. Ethics

• There is the potential to behave unethically in research
• This is constant and it does not just depend on particular situations or methods
