Congrats!

I DID IT! Holy cow! That was hard... That felt really good hitting the test button for the 100th time and seeing all green. Wow..

Ok, why not [8,1] in {19, 9, 10, 4', 5, 4, 6, 3, 2'', 1, 4, 1, 3, 2, 4} 2=>1this is rigth leaf (summ=4 leaf:{3,2'} rigth=>1)
{29, 13, 16', 5, 8, 9, 1''} this 1=9 this is rigth leaf (summ=16 leaf:{9,1'}rigth=>7)

'This is because of the condition "if the incorrect value occurs on the leaf level, then the right child will always be the incorrect one." Since 9 + 1 != 16, the 1 must be changed to 7, rather than changing the 9 to 15.'

{19, 9, 10, 4, 5, 4, 6, 3, 2, 1, 4, 1, 3, 2, 4} answer - [3,5] incorect parents.
But!
{29, 13, 16, 5, 8, 9, 1} answer - [6.7] ! incorect leaf.
Absolutly equal case give different results?
I'm sorry, i'm not understand.

O_o
the picture confused me - the root is at the top and the leaves are at the bottom ...
