Solution: Compilation Order
Explore how to determine the correct compilation order of classes based on dependency pairs using topological sort. Understand graph construction, in-degree tracking, and BFS traversal to solve dependency problems efficiently. Gain insights into detecting cycles and ensuring valid orderings 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 an array of the dependency pairs, find the order in which the classes should be compiled.
Constraints:
- Class name should be a character.
