题意：略。

析：答案就是32^n。

代码如下：

import java.math.BigInteger;
import java.util.Scanner;

public class Main{
	public static final int maxn = 3000 + 5;
	public static BigInteger []ans;
	
	public static void main(String[] args){
		Scanner cin = new Scanner(System.in);
		int T = cin.nextInt();
		ans = new BigInteger[maxn];
		ans[0] = BigInteger.ONE;
		for(int i = 1; i <= 3000; ++i)
			ans[i] = ans[i-1].multiply(BigInteger.valueOf(32));
		for(int kase = 1; kase <= T; ++kase){
			int n = cin.nextInt();
			System.out.println("Case #" + kase + ": " + ans[n]);
		}
	}
}
