思路：大数的连乘。

java代码：

import java.math.BigInteger;
    import java.util.*;
    import java.io.*;
 
 
public class Main {
 
 
    public static void main(String[] args) {
        Scanner cin = new Scanner (System.in);
        int t = cin.nextInt();
        BigInteger ans = cin.nextBigInteger();
        for(;t>1;t--){
            BigInteger a = cin.nextBigInteger();
            ans = ans.multiply(a);
        }
        System.out.println(ans);;
    }
     
     
}

 Python 3 代码：

n = int(input())
 
res = 1
for i in range(n):
    res *= int(input())
 
print(res)
