218e21e800 Update stack.md (#1788) 
* Update stack.md

K大好，小白建议在这句话前面增加一个条件 -- "每次只能移动一个盘子"，如此不仅可以对应后面的 `将上面的盘子**依次**移走`，从而避免了 "可以将上面的盘子一次移走" 的歧义；而且对应了每次移除一个元素的出栈逻辑。

* Refine explanation of stack data structure

Corrected phrasing for clarity in stack explanation.

5c085b5592 Update performance_evaluation.md (#1770) 
* Update performance_evaluation.md

**修改内容：**
把本节使用的 “输入数据大小” 统一修改为 “输入数据规模”。

**修改原因：**
今天在分析一个函数的复杂度时回看本节，发现这处表述好像存在歧义。阅读本节内容可知，复杂度分析实际是分析算法的运行时间和空间占用与数据规模的关系。 从字面理解，“输入数据的大小” 更像指输入数据的数值大小，而非数据规模。虽然多数场景下，输入数据的数值大小可以通过迭代/递归反映数据规模，但在个别场景下并非如此，如 5.1.2 节 "基于链表实现的栈" 中的 `to_list() `函数:
```python
 def to_list(self) -> list[int]:
        """转化为列表用于打印"""
        arr = []
        node = self._peek
        while node:
            arr.append(node.val)
            node = node.next
        arr.reverse()
        return arr
```
该函数无形参，其时间复杂度实际指，函数运行时间随着栈中数据数量的增加而呈现的增长趋势，而非随栈中数据数值大小的增加呈现的增长趋势。 因此，为规避歧义，小白提议将本节的“输入数据大小” 改为 “输入数据规模”。

然而，一百个读者有一百个哈姆雷特，或许其他读者读到这里未感觉歧义，且本章后续章节还有多处使用这一表述，若本节修改可能后面也需与其保持统一。或许也可以在本章2.1节插入一个Tip约定这一表述的实际意义。考虑不周，欢迎 K大及评阅大佬指正！

* Update time_complexity.md

对于多项式函数 c * f(n)， 系数 c 好像不能称为常数项，遂查阅《算法导论 第三版》相关章节，在其 26 页使用了常量因子这一表述，该表述好像晦涩了些，小白提议这里将 ”常数项“ 改为 ”常数“。

6a4d62449c Update max_product_cutting_problem.md (#1758) 
* Update max_product_cutting_problem.md

本节结尾的正确性证明中，

"使用反证法，只分析 n >= 3 的情况。"

这句是否应该改为 “只分析 n >= 4 的情况”，因为 n == 3 时，由于题目要求至少将 n 切分为两个正整数，所以此时应该切分为 1 * 2 ，切分方案里是包含 1 的 😁；
此外，对于这句描述：

“假设最优切分方案中存在 >= 4 的因子 x ，那么一定可以将其继续划分为 2(x-2) ，从而获得更大的乘积。”

最后半句改为“从而获得更大或可替代的乘积”是否更好，因为当切分方案中存在 4 作为因子时，将其划分为 2 * 2，乘积相对划分前是相等的。不过这处改动不影响“所有因子 <= 3” 的结论，因为因子 4 是可以被替代的。

* Update max_product_cutting_problem.md
