Write a function that takes a string as input and returns the string reversed.
Example:
Given s = "hello", return "olleh".
思路:
利用Java的StringBuilder类,其中有内置的reverse()方法,之后再转为String类即可。
解法:
1 public class Solution 2 { 3 public String reverseString(String s) 4 { 5 StringBuilder stringBuilder = new StringBuilder(s); 6 stringBuilder.reverse(); 7 return stringBuilder.toString(); 8 } 9 }
