//编写一个函数,其作用是将输入的字符串反转过来。输入字符串以字符数组 char[] 的形式给出。 // // 不要给另外的数组分配额外的空间,你必须原地修改输入数组、使用 O(1) 的额外空间解决这一问题。 // // 你可以假设数组中的所有字符都是 ASCII 码表中的可打印字符。 // // // // 示例 1: // // 输入:["h","e","l","l","o"] //输出:["o","l","l","e","h"] // // // 示例 2: // // 输入:["H","a","n","n","a","h"] //输出:["h","a","n","n","a","H"] // Related Topics 递归 双指针 字符串 // 👍 422 👎 0 package leetcode.editor.cn; //344:反转字符串 public class ReverseString { public static void main(String[] args) { //测试代码 Solution solution = new ReverseString().new Solution(); } //力扣代码 //leetcode submit region begin(Prohibit modification and deletion) class Solution { public void reverseString(char[] s) { int length = s.length; int size = length % 2 == 0 ? length / 2 : length / 2 + 1; for (int i = 0; i < size; i++) { char temp = s[i]; s[i] = s[length - 1 - i]; s[length - 1 - i] = temp; } } } //leetcode submit region end(Prohibit modification and deletion) }
