You are given a binary tree in which each node contains an integer value. Find the number of paths that sum to a given value. The path does not need to start or end at the root or a leaf, but it must go downwards (traveling only from parent nodes to…

题目 Follow up for "Find Minimum in Rotated Sorted Array": What if duplicates are allowed? Would this affect the run-time complexity? How and why? Suppose a sorted array is rotated at some pivot unknown to you beforehand. (i.e., 0 1 2 4 5 6 7 migh…

Given a binary tree and a sum, determine if the tree has a root-to-leaf path such that adding up all the values along the path equals the given sum. For example:Given the below binary tree and sum = 22, 5 / \ 4 8 / / \ 11 13 4 / \ \ 7 2 1 return true…

Given a binary tree and a sum, find all root-to-leaf paths where each path's sum equals the given sum. For example:Given the below binary tree and sum = 22, 5 / \ 4 8 / / \ 11 13 4 / \ / \ 7 2 5 1 return [ [5,4,11,2], [5,8,4,5] ] 112. Path Sum 的拓展,上一…

If the depth of a tree is smaller than 5, then this tree can be represented by a list of three-digits integers. For each integer in this list: The hundreds digit represents the depth D of this node, 1 <= D <= 4. The tens digit represents the positio…

\(Maximum\) \(Minimum\) \(identity\)学习笔记 比较好玩的一个科技.具体来说就是\(max(a,b)=a+b-min(a,b)\),这个式子是比较显然的,但是这个可以扩展到更多数字,比如说\(max(a,b,c)=a+b+c-min(a,b)-min(a,c)-min(b,c)+min(a,b,c)\),其实就是容斥一下.这个东西的用处就是直接求\(max\)比较难求,转化成求\(min\). 例题\(1\): \(bzoj\) \(4036\). 首先根据\(…
