Solve the following python programming problem given the following code:
# Definition for a binary tree node.
# class TreeNode(object):
#     def __init__(self, x):
#         self.val = x
#         self.left = None
#         self.right = None

class Solution(object):
    def findLeaves(self, root):
        """
        :type root: TreeNode
        :rtype: List[List[int]]
        """
        result = []
        self.dfs(root, result)
        return result
    
    def dfs(self, root, result):
        if root is None:
            return 0
        
        level = max(self.dfs(root.left, result), self.dfs(root.right, result)) + 1
        if level > len(result):
            result.append([])
        result[level-1].append(root.val)
        return level
