The following python code describes an algorithm for inserting values into a binary search tree.
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 

Using this algorithm, you create a new binary search tree B, and insert the following elements into it in this order:
1 

After these operations, what is the sum of the data in the leaf nodes of B?
Details and assumptions
A leaf node is a node that has no children (no left_child
or right_child
).
sequence of 30 integers, determine how many subsets (including the empty one) have a sum between 700 and 700 inclusive.
In the followingHow many 16digit integers are there such that the sum of the square of their digits is a square?
Examples And Test Cases
$2283$ is a $4$digit integer such that the sum of the square of its digits is a square. $2^2 + 2^2 + 8^2 + 3^2 = 81 = 9^2$.
There are $332$ $4$digit integers with the required property.
