Solution: Compilation Order
Understand how to solve the class compilation order problem by applying topological sort. Learn to build a graph of class dependencies, identify sources and sinks, and produce a valid linear ordering of compilation. Explore optimized breadth-first search techniques to manage dependencies and detect cycles, ensuring you can implement this vital pattern in coding interviews.
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.
