最长递增子序列

最长递增子序列（LongestIncreasingSubsequence，简写LIS）是动态规划比较经典的一个问题。先定义一个dp数组：dp[i]表示以nums[i]这个数结尾的最长递增子序列的长度。

题意：找出最长上升连续子序列（5，6，7，8...）题解：直接用一个map映射每一个的值，递推计算出以每个值为结尾的序列长度，另外有很多map是未初始化的，大概在cf上都默认为0；一开始用了O(n^2)的LIS改了条件保存路径输出，TLE了，后来用了排序递推，WA了#includeusingnamespacestd;intarr[200100],N,r,k,last,t,i;mapm;intmai

题意：给一个数字字符串s和t，求s中有多少个子序列比t更大题解：如果子序列比t更长，那么只要开头不是0都可以，暴力枚举做这件事就好了。问题在于子序列和t等长的情形。从前往后考虑很麻烦，试着从后往前考虑：dp[i][j]表示的是s中以i开始的后缀的子序列匹配了t的j以后的子串。于是有:$$dp[i][j]=\begin{cases}dp[i+1][j]+dp[i+1][j+1]&s[i]=t[j]\
