Solution: Compilation Order
Explore how to solve class compilation order problems by applying topological sort. Understand dependency management, graph construction, and how to detect cycles in this coding interview pattern. Gain skills to determine valid compilation sequences with optimized time and space complexity.
Statement
There are a total of classes labeled with the English alphabet (, , , and so on). Some classes are dependent on other classes for compilation. For example, if class extends class , then has a dependency on . Therefore, must be compiled before .
Given a list of the dependency pairs, find the order in which the classes should be compiled.
Constraints:
- Class name should be an uppercase character.
