Input: s = “abcdefg”, k = 2 Output: “bacdfeg” Restrictions: The string consists of lower English letters only. Length of the given string and k will in the range [1, 10000] 本题题意十分简单,就是做一个字符串的反转,注意是没2k个子串中前k个反转,其余的不变 建议和leetcode 344. ...

public String reverseStr(String s, int k) { char[] arr = s.toCharArray(); int n = arr.length; int i = 0; while(i < n) { int j = Math.min(i + k - 1, n - 1); swap(arr, i, j); i += 2 * k; } return String.valueOf(arr); ...
2、代码实现 public class Solution { public String reverse(String s) { if (s == null || s.length() == 0) { return null; } char[] chars = s.toCharArray(); int length = chars.length; int start = 0, end = length - 1;
