一个数的因数

“数字因数”问题的详细指南和 Python 实现。

问题陈述

简单

编写一个函数 find_factors(n),它接受正整数 n 并按升序返回 n 的所有因子(除数)的列表。 n 的因子是除 n 且不留余数的任何正整数。

约束条件
  • 1 <= n <= 10^6

示例

Example 1
Input
n = 12
Output
[1, 2, 3, 4, 6, 12]
Explanation

12 is divisible by 1, 2, 3, 4, 6, and 12.

Example 2
Input
n = 7
Output
[1, 7]
Explanation

7 is prime, so its only factors are 1 and 7.

Example 3
Input
n = 1
Output
[1]
Explanation

The only factor of 1 is 1 itself.

Need a Hint?
考虑使用特定于基础的数据结构,例如集合或堆。
Edge Cases to Watch
  • 空输入结构
  • 单元素输入
  • 大数值范围
