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.
No, it should be like you say:
X_5 = [3, 3, 3] # -> X_5[0] = X_4[0] - X_4[1] = 6 - 3It should have been like this "X_5 = [3, 3, 3] # -> X_5[0] = X_4[0] - X_4[1] = 6 - 3" instead of this "X_5 = [3, 3, 3] # -> X_5[1] = X_4[0] - X_4[1] = 6 - 3" in the example which is given in instructions.
Second element of array is assigned according to the example: "X_5[1] = X_4[0] - X_4[1]". Then, if you look at the result, first element is the one which is assigned. "X_5 = [3, 3, 3]". Am I missing something?
