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.
So in (209917, [29917, 0, 1]), it moved '0' to far left to make the smallest number, but in (269045, [26945, 3, 0]), it moved '2' to the index of '0' to make the smallest number. I do not see how the mechanism changes by test cases :(
I am not sure what the problem exactly wants.
This is what I console.log() -ed
arr => two,six,five,seven,three,nine ..//.. value => three
and it returned [Should not find 'three']
There was also [not find element on 1st level] which I do not get at all. Does this mean I should not be looking for the value on the 1st level?
Thanks!
