Solution: Compilation Order
Understand how to find a valid compilation sequence for classes with dependencies using topological sort. Explore graph construction, in-degree tracking, and BFS traversal to generate a linear order that respects the compilation requirements, while managing cycles and optimizing 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 a character.
