Solution

The output of the given code snippet will be 15.

Here's how:

The calculate_sum function is a recursive function that sums up the data of the given node and the sums of its left and right children. If a node is None (i.e., it doesn't exist), it contributes 0 to the sum.

The tree structure created by the usage example is as follows:

    1
   / \
