What are the differences between linear and binary search?
Linear: Checks each element sequentially, works on unsorted data | Binary: Requires sorted data, eliminates half the data with each step.
What are the differences between parameters and arguments?
Parameters: Variables in procedure definition | Arguments: Values passed when calling the procedure.
What are the differences between reasonable and unreasonable time complexity?
Reasonable: Polynomial or lower | Unreasonable: Exponential or factorial.
What are the differences between decidable and undecidable problems?
Decidable: An algorithm can always find a solution | Undecidable: No algorithm can always find a solution.
