Solution: Compilation Order
Explore how to determine the compilation order of classes dependent on one another using topological sort. Learn to build a graph of dependencies, identify sources, and find a valid linear order that respects all dependency constraints while detecting cycles.
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.
