 BST Level Sum
Question:
Mr. Uka is having a research. On his research, he is
using Binary Search Trees. And, he has to calculate
the sum of the nodes in the given level.
For some reason, the tree can grow very deep, and,
this causes problems. Thus, he wants to limit the
depth to a certain value. The nodes which go deeper
than the given limit will be ignored.
Write a program that is going to read the
given list of values, and insert them into the BST.
And calculate the sum of the nodes in the given level.
Input specification:
In the first line, you will be given three integers:
- max depth: an integer between 0 and 15
- Sum level: the level to calculate the sum of
the numbers, an integer between 0 and 15
- n: the number of the elements in the following
line to insert into BST; an integer between 0 and 50000
Output specification
Show sum of the numbers in the given level.
Note: If there exists a number in
BST, the number will be ignored.
| Sample Input I |
Sample Output I |
2 1 10
6 2 4 8 5 2 3 7 4 1
|
10
