Hi, here's your problem today. This problem was recently asked by Google:
By the way, check out our NEW project AlgoPro (http://algopro.com) for over 60+ video coding sessions with ex-Google/ex-Facebook engineers.
You are given a hash table where the key is a course code, and the value is a list of all the course codes that are prerequisites for the key. Return a valid ordering in which we can complete the courses. If no such ordering exists, return NULL.
Example:
This input should return the order that we need to take these courses:
['CSC100', 'CSC200', 'CSCS300']
Here's your starting point:
