167. Two Sum II - Input array is sorted[easy] Given an array of integers that is already sorted in ascending order, find two numbers such that they add up to a specific target number. The function twoSum should return indices of the two numbers such…
先求出SAM,然后考虑定义,点u是一个right集合,代表了长为dis[son]+1~dis[u]的串,然后根据有向边转移是添加一个字符,所以可以根据这个预处理出si[u],表示串u后加字符能有几个本质不同子串 然后回答的时候在树上跑一下即可 #include<iostream> #include<cstdio> #include<cstring> using namespace std; const int N=300005; int n,m,fa[N],ch[N][…
You are given a string, s, and a list of words, words, that are all of the same length. Find all starting indices of substring(s) in s that is a concatenation of each word in words exactly once and without any intervening characters. For example, giv…
This is a problem from ZOJ 2432.To make it easyer,you just need output the length of the subsequence. InputEach sequence is described with M - its length (1 <= M <= 500) and M integer numbers Ai (-2^31 <= Ai < 2^31) - the sequence itself.Outpu…
Given an array of integers that is already sorted in ascending order, find two numbers such that they add up to a specific target number. The function twoSum should return indices of the two numbers such that they add up to the target, where index1 m…
LCS2 - Longest Common Substring II no tags A string is finite sequence of characters over a non-empty finite set Σ. In this problem, Σ is the set of lowercase letters. Substring, also called factor, is a consecutive sequence of characters occurrence…
