Solution: Compilation Order
Explore how to apply topological sorting to find the proper compilation order of classes based on their dependencies. Learn to build a graph, track in-degrees, and use breadth-first search to generate an order that respects dependency constraints, while handling potential cycles to ensure a valid solution.
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 ...
