给你一个仅由大写英文字母组成的字符串,你可以将任意位置上的字符替换成另外的字符,总共可最多替换 k 次.在执行上述操作后,找到包含重复字母的最长子串的长度.注意:字符串长度 和 k 不会超过 104.示例 1:输入:s = "ABAB", k = 2输出:4解释:用两个'A'替换为两个'B',反之亦然.示例 2:输入:s = "AABABBA", k = 1输出:4解释:将中间的一个'A'替换为'B',字符串变为 "AABBBBA".子串 &qu…

以最左边为开始,往右遍历,不一样的个数大于K的时候停止,回到第一个不一样的地方,以它为开始,继续.. 用QUEUE记录每次不一样的INDEX,以便下一个遍历开始, 从左往右,从右往左各来一次..加上各种剪枝情况,比如未遍历的数量<剩余K的数量,比如已经记录过某个INDEX了.. 然后TLE了...最后放TLE的方法..不知道有什么意义.. 上面的做法是左右各来一次,那是否可以使用滑窗呢.. 然后没做出来..看了讨论区..果然是滑窗.. 思路: 统计当前滑窗内最多的字母,窗口宽度 - 最多字母数量…
