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.
You could also have use Math.min() and Math.max() to know the smaller and greater numbers
For Go version, we call the methods like that:
canvas.MoveTo
canvas.LineTo
Occasionally, I have problems with solution saving on PHP either.
PHP out of memory :-(
