Given a strings, return the last substring ofsin lexicographical order. Example 1: Input:"abab" Output:"bab" Explanation: The substrings are ["a", "ab", "aba", "abab", "b", "ba", "bab"]. The lexicographically maximum substring is "bab". Example 2: Input:"leetcode" Output:"tcod...
Explanation: The lexicographical order is [1, 10, 11, 12, 13, 2, 3, 4, 5, 6, 7, 8, 9], so the second smallest number is 10. 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. 12. 13. 14. 第一次做; 直接看的leetcode题解; 核心:字典序排列也就是对十叉树进行先序遍历 class S...

输入:s = "leetcode" 输出:"tcode" 提示: 1 <= s.length <= 4 * 105 s 仅含有小写英文字符。通过次数 24.6K 提交次数 69.7K 通过率 35.3%相关标签双指针字符串相关企业 提示1 Assume that the answer is a sub-string from index i to j. If you add the character at index j+1 you get...
Input:"leetcode"Output:"tcode" Note: 1 <= s.length <= 10^5 s contains only lowercase English letters. 思路:因为s只有lower case,所以直接考虑按位来考虑 1. 首先开头第一个字母一定是s中最大的char 2. 维护一个index数组表示可能的结果(假设数组内的值为1,5,7,那结果就是从s[1:],s[5:],...
