下面我们给出代码,我们需要处理某些特殊情况,例如输入字符串为空串等等。 int lengthOfLongestSubstring(string s) { int pos[26]; int i; for(i=0;i<26;i++) { pos[i]=-1; } int basePos=0; int maxLength=-1; for(i=0;i<s.length();i++) { if(pos[s[i]-'a']maxLength) maxLength=i...
代码 def find_lcsubstr(s1, s2): m = [[0 for i in range(len(s2) + 1)] for j in range(len(s1) + 1)] # 生成0矩阵,为方便后续计算,比字符串长度多了一列 mmax = 0 # 最长匹配的长度 p = 0 # 最长匹配对应在s1中的最后一位 for i in range(len(s1)): for j in range(len(s2...
Given a string s, find the longest palindromic substring in s. You may assume that the maximum length of s is 1000. Example: Input: "babad" Output: "bab" Note: "aba" is also a valid answer. Example: Input: "cbbd" Output: "bb" ...
This is a like a sliding window to find the longest substr, if we put the letters in an array, then check the next letter, if it is in the array, then sliding the window, otherwise, put the value in the array set. code:
