数字颠倒

思路比较简单，做了这几条，就这一条能一眼看出来的。直接当作String倒序就行：
import java.io.IOException;
import java.io.InputStream;
import java.io.BufferedReader;
import java.util.*;
public class Main {
public static void main(String[] args) throws IOException {
Scanner scanner = new Scanner(System.in);
String s = scanner.nextLine();
char[] chars = s.toCharArray();
for (int i = chars.length-1; i >=0 ; i--) {
System.out.print(chars[i]);
}
System.out.println();
}
}
