五个字乘以4等于倒过来的值,四个字乘以4等于倒过来的值

//例：我爱写代码*4=码代写爱我

//结果：我=2   爱=1  写= 9 代=7 码=8

public class test {
public static void main(String[] args) {
long a = 1;
for(int i=1;i<30000;i++){
StringBuffer sb = new StringBuffer();
a = i*4;
sb.append(i);
String s = sb.reverse().toString();
long b = Integer.parseInt(s);
if(a == b && a>9999){ 
System.out.println(i);
}
}
}
}
