DART (Define, Analyze, Resolve, Test) interview, solving problems involves an approach to ensure clarity and completeness.
Here are the startegies :
1. Define the Problem
For every problem to be solved thorougly you need to understand the problem. Understand and paraphrase every section to confirm. Determine inputs, outputs, and other factors that are relevant with unusual and extereme scenarios.
2. Analyze the Problem
Here you weill break the problems into sub-problems for managing parts to resolve the issues with the sections related to each other. You will also need to decide on the data structures and algorithms that will fit the best with each considering time and space complexity.
3. Resolve the Problem
In this startegy you will resolve the problem one after another you can sketch it out for bigger problems. You can start writing small code and increment it as you go further, the code should be clean and easy to understand.
4. Test the problem
Testing the problem can be done one after another like the unit testing for individual components and altogether that is intergrated testing. Optimizing the code with changing behaviour and validating edge cases are done in this phase.
