Leetcode 1450 Solution

This article provides solution to leetcode question 1450 (delete-leaves-with-a-given-value)



# Definition for a binary tree node.
# class TreeNode:
#     def __init__(self, val=0, left=None, right=None):
#         self.val = val
#         self.left = left
#         self.right = right
class Solution:
    def removeLeafNodes(self, root: TreeNode, target: int) -> TreeNode:
        if not root:
            return None

        root.left = self.removeLeafNodes(root.left, target)
        root.right = self.removeLeafNodes(root.right, target)

        if not root.left and not root.right and root.val == target:
            return None
            return root
