The costs associated with finding a desired solution to a problem can typically include:
- Efficiency - This refers to how effectively a solution can be found in relation to time and resources used.
- Solution costs - This embodies the various costs associated with implementing a solution, such as time, resources, and effort.
- Resource constraints - These are limitations on available resources, which can affect the ability to explore all potential solutions.
"Unsorted array" does not represent a cost associated with finding a solution; rather, it is a data structure issue.
So the relevant costs from your list would be:
- Efficiency
- Solution costs
- Resource constraints
