Loading collection data...
Collections are a way for you to organize kata so that you can create your own training routines. Every collection you create is public and automatically sharable with other warriors. After you have added a few kata to a collection you and others can train on the kata contained within the collection.
Get started now by creating a new collection.
Ok, duly noted!
yes
These katas are not identical at all.
Very easy with built in python functions. Also is this the exact same problem as this https://www.codewars.com/kata/571bff6082661c8a11000823?
Then perhaps the difficulty of either one of them should be changed?
I have no clue what Djikstra is, but I've been sweating for days to solve this one! Wouldn't really call it easy. Both implementationwise buth espacially algorithwise I would say that it is by far the most challening level 4 kata I've done.
Well well, over now :)

I'll do a bet: you're using Djikstra? not a good approach here: this algo does way more work than you actually need (this kata is actually rather easy, for a 4 kyu. That is, as long as you use a well chosen algorithm... ;p )

Confusing with the long long. Was there a need for this?
brilliant!
Kudos to the people that actually thought about the mathematics behind the question. I feel stupid now...
