In this video I am dusting off my Leetcode skills and my microphone and making my first video in what feels like forever. Luckily we have a not so difficult graph problem using a familiar topological sort algorithm.

On line number 22, shouldn't it return -1 instead of 1 since we know it is cyclic now? Leetcode's 2nd test case relation: [[1,2],[2,3],[3,1]] is failing if 1 is returned. -1 works well and submission is passing for me Coding in Swift.

Hmm yea I think so! Strange that it works for either -1 and 1 in Python. Good catch
