The this exercise times out. I’ve locally tested my code with all test cases and they all complete in under 100ms with correct results.
I’m converting the input to a bidirectional graph and using BFS so it should be pretty fast.
There are some infrastructure issues (related to Denial of Service attacks) and the site is under heavy load. This is likely the cause and not your code.
Is there a way to bypass validation of the exercise and continue the track since it’s a required exercise?
I believe you can mark it complete if you submit it using the CLI. However, this is a newer exercise. It shouldn’t be blocking other exercises.
