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.

For this test, goldMineRace([[1,6], [1,-4], [-4,1], [11,1], [4,5]],[1, 1, 1, 2, 1],[1, 1]),-1)
I wonder whether the answer should be 4, the last city? Why? Well, I think the first four cities' armies arrive at the same time, so they wipe each other out; then the last city, index 4, arrives and gets the gold mine.
city[0] has to go 5 at a speed of 1
city[1] has to go 5 at a speed of 1
city[2] has to go 5 at a speed of 1
city[3] has to go 10 at a speed of 2
city[4] has to go 7 at a speed of 1, so it arrives last, but alone. What am I missing here?
This is a terrible kata. The description is very unclear; I wasted several hours on it; waste of time!
Sorry, but I had the same question, and I do not see why your question is wrong. '3452' is shorter than 'wkppv'. Why is the former included and not the latter?
