Binary Tree Level Order Traversal II
Given a binary tree, return the bottom-up level order traversal of its nodes' values. (ie, from left to right, level by level from leaf
to root).
For example:
Given binary tree
return its bottom-up level order traversal as:
Solution:
Reverse the result of Binary Tree Level Order Traversal.
LeetCode Binary Tree Level Order Traversal
Given a binary tree, return the bottom-up level order traversal of its nodes' values. (ie, from left to right, level by level from leaf
to root).
For example:
Given binary tree
{3,9,20,#,#,15,7},3 / \ 9 20 / \ 15 7
return its bottom-up level order traversal as:
[ [15,7] [9,20], [3], ]
Solution:
Reverse the result of Binary Tree Level Order Traversal.
