Solution: Compilation Order
Explore how to determine the correct compilation order of classes by applying topological sort. This lesson guides you through building a graph from class dependencies, using BFS to find sources, and detecting cycles, helping you understand and implement an efficient solution for dependency-based ordering problems.
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.
