求string str1中含有string str2 order的 subsequence 的最小长度 DP做法:dp[i][j]定义为pattern对应到i位置,string对应到j位置时,shortest substring的长度,Int_Max表示不存在 package ShortestSubsequenceIncluding; public class Solution { public String findShortest(String a, String b){ if(a==nul…
求问下各位大神,怎么判断一个按照Preorder traversal serialized的binary tree的序列是否正确呢?不能deserialize成树比如 A) 9 3 4 # # 1 # # 2 # 6 # #是对的,因为表示 9 / \ 3 2 / \ \ 4 1 6 B ) 9 3 4 # # 1 # #就是错的,因为无法反构造回一棵树 我觉得可以在字符串里找"n##"这种结构(对应tree里两个children都是Null的叶节点),找到之后就把"n##&…

题目描述 HZ偶尔会拿些专业问题来忽悠那些非计算机专业的同学.今天测试组开完会后,他又发话了:在古老的一维模式识别中,常常需要计算连续子向量的最大和,当向量全为正数的时候,问题很好解决.但是,如果向量中包含负数,是否应该包含某个负数,并期望旁边的正数会弥补它呢?例如:{6,-3,-2,7,-15,1,2,2},连续子向量的最大和为8(从第0个开始,到第3个为止).你会不会被他忽悠住?     Given a sequence of K integers { N1, N2, ..., NK }.…
