Question
Which of the following is a characteristic of "tight
coupling" between software modules?Solution
Tight coupling means that modules are highly dependent on each other. A change in one module's internal implementation or interface often necessitates changes in other modules that depend on it. This makes systems harder to maintain, test, and reuse. Loose coupling, where modules interact through stable interfaces, is generally preferred.
Which of the following properties must a problem exhibit to be solvable by a greedy algorithm?
