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.

Alright... after switching things the wrong way i've switched them right :)
Thanks for pointing that out... fixed it.
do the inputs always contain the correct number of values? because im getting an "index out of range error" on two of the tests (not the sample ones). This is in python>
A key part to this problem that makes it much easier is that you can only move right or down. If you could move in any direction(up, down, left, or right)how would you go about solving it. Would it be neccasary to calculate every possible path(which would probably become impossible with bigger arrays) or is there some other way?
I tried this with sequence.back() - 1 instead of sequence.at(sequence.size() - 2), but for some reason it didnt work, why?
