求看代码，头条笔试第二题为何通过是0。。。

# -*- coding:utf-8 -*- import sys

n = int(sys.stdin.readline().strip())
seq = [int(num) for num in sys.stdin.readline().strip().split()]

seq.sort(reverse=True)
max_value = seq[0]
last = seq[0] for i in range(1, n): if (max_value + seq[i])*seq[i] > max_value*last:
      max_value += seq[i]
      last = seq[i]
max_value *= last print(max_value)
