Define the functionadd_trees, which takes in two trees and returns a new tree where each corresponding node from the first tree is added with the node from the second tree. If a node at any particular position is present in one tree but not the other, it should be present in the new ...

if the stack has one item, and there are no more values to squeeze in, you have a valid expression. if the stack is two or more deep, then you can add to expression by using an operator to combine those top two values, and the stack is now one shallower. if you have more values...

求Uni-value subtree的个数。对树来说这求count的首先思路就是递归了,不过这里要另外构造一个辅助函数来判断root为顶点的subtree是否是Uni-value subtree,假如是Uni-value的subtree,则结果可以+1,否则,我们返回递归求出的左子树的count和右节点的count。假如是Python的话可以一边计算一边返回。Java写起来可能稍微麻烦点...
Atreeis a data structure that consists of one or more nodes organized into a hierarchy. The tree has oneroot, which is the top node. All nodes except the root have a uniqueparent. The node labeled*in the picture below is aparent. Nodes labeled2and7are itschildren; children are ordered ...
