To achieve this, you can implement a recursive algorithm to traverse the binary tree and identify paths that sum to the specified value. Here's a Python example using a binary tree node structure:
```python
class TreeNode:
def __init__(self, value):
self.value = value
self.left = None
self.right = None
def print_paths_with_sum(root, target_sum):
def find_paths(node, current_path, current_sum):
if not node:
return
current_sum += node.value
current_path.append(node.value)
if current_sum == target_sum:
print(current_path)
find_paths(node.left, current_path.copy(), current_sum)
find_paths(node.right, current_path.copy(), current_sum)
if not root:
return
find_paths(root, [], 0)
# Example usage:
# Create a binary tree
root = TreeNode(10)
root.left = TreeNode(5)
root.right = TreeNode(-3)
root.left.left = TreeNode(3)
root.left.right = TreeNode(1)
root.right.right = TreeNode(11)
root.left.left.left = TreeNode(3)
root.left.left.right = TreeNode(-2)
root.left.right.right = TreeNode(2)
# Specify the target sum
target_sum = 8
# Print paths with the specified sum
print_paths_with_sum(root, target_sum)
```
This code defines a binary tree node class and a method `print_paths_with_sum` that recursively traverses the tree, finding and printing paths that sum to the specified value. The `find_paths` function is a helper function that does the recursive exploration.
