假设当窗口的右边界向右滑动添加一个字符后,窗口中的子串存在重复的字符,按照解法二的方法,则会将窗口的左边界向右滑动一个字符直到窗口中不存在重复字符为止。这样的做法其实是不高效的,比如重复的字符位于子串的右半部分,那么至少需要迭代len(substring)/2len(substring)/2次才能使得窗口包含的子串不包含重复的字符。
Given “pwwkew”, the answer is “wke”, with the length of 3. Note that the answer must be a substring, “pwke” is a subsequence and not a substring. 题意就不说了,这道题是求的是最大的不重复的子串,求解重复子串可以类似采用最长公共子串的解法。 最长重复子串在这里指的是在只一个字符...
