Today, I will talk to you about how to analyze the summation of python binary tree paths. Many people may not know much about it. In order to make you understand better, the editor has summarized the following contents for you. I hope you can get something according to this article.

Title

Given a binary tree, find out the paths in which the sum of the nodes in all paths is equal to the given target value.

A valid path refers to the path from the root node to the leaf node.

Solution

This problem can be solved by recursive backtracking. On the one hand, the recursive traversal depth can be used to give priority to the whole tree, passing in the recursive search from the root node to the sum of all the elements in the current node path and the nodes on the path. Once a leaf node is found to determine whether the current path sum is equal to target, then a legal path is found. Put it in the answer.

After reading the above, do you have any further understanding of how to analyze the summation of python binary tree paths? If you want to know more knowledge or related content, please follow the industry information channel, thank you for your support.
