滴滴第二题R的n次方，大胆猜测，样例给错了hdu1063

import java.math.BigDecimal;
import java.util.Scanner;
public class Main{
public static void main(String[] srgs){
Scanner in = new Scanner(System.in);
while (in.hasNext()) {//注意while处理多个case
BigDecimal r = in.nextBigDecimal();
int n = in.nextInt();
BigDecimal ans = r;
for(int i = 1; i < n; ++i){
ans = ans.multiply(r);
}
ans=ans.stripTrailingZeros();
String str=ans.toPlainString();
System.out.println(str);
}
}
}
