344. Reverse String
Write a function that takes a string as input and returns the string reversed.
反转string字符串
java代码:
public class Solution {
public String reverseString(String s) {
String a="";
StringBuilder sb=new StringBuilder(a);
for(int i=0;i<s.length();i++){
sb.insert(0,s.charAt(i));
}
return sb.toString();
}
}
第二种解法，更加快速
java代码:
public class Solution {
public String reverseString(String s) {
char[] ch=s.toCharArray();
int i=0;
int j=s.length()-1;
char temp;
while(i<j){
temp=ch[i];
ch[i++]=ch[j];
ch[j--]=temp;
}
return new String(ch);
}
}
