I tried to solve a classic probjem by using dijkstra with set, but got TLE.
I could not find out the reason why. Here is my code: Submission 65475444
Can you suggest any reasons? Thank you!

I just tinkered your solution a little bit and the reason I think you are getting TLE may be due to accessing pair elements more than once I just stored them in variables. For your curiosity, I made the same mistake xd and also you can speed this up using priority queue more here.
cheers :)
That's helpful. Thank you!
