Topological sort implementation
- [Instructor] This lesson will dive into JavaScript code that demonstrates topological sorting. We'll also discuss converting edge lists to an adjacency list, which is crucial for efficiently managing the graph representation. By understanding and implementing this algorithm, you can determine a valid sequence of tasks and projects where dependencies exist, ensuring that all prereqs are addressed before moving forward. We'll walk through each step carefully. Here I have to find the node class that is a graph node, which I will be using inside the topological sort implementation. Here is an input, which is a 2D array, representing an edge list. Each sub array in this input is the from and to, which represents the prerequisite tree above. For example, you must take Class D to take Class J, so on and so forth. And there is the topological sort function that takes in an edge list, which we will fill in. Firstly, since the input is an edge list, we need to convert it into an adjacency…
