一篇读懂采样参数：temperature 与 top-p 是怎么给模型「调性格」的
同一个模型，temperature 从 0.2 调到 1.2，可以从「背答案的图书馆员」变成「喝了两杯的诗人」——模型一个参数都没变，变的只是从概率分布里挑词的规则。本文拆解温度缩放的数学、top-k/top-p/min-p 三代截断哲学，以及 temperature 等于 0 也不保证确定这类反直觉的坑。

一篇读懂 Temperature 与 Top-p：采样参数怎么调
模型每步输出的不是「下一个字」而是一张概率表，Temperature 与 Top-p 决定怎么从表里抽签。本文讲清温度如何改变分布锐度、Top-p 如何动态截断候选、重复惩罚如何抑制复读，并给出代码、问答、写作、Agent 四类场景的参数对照表。

LeetCode 215. 数组中的第 K 个最大元素：不排序，怎么选出第 k 名
「找出第 k 大」是生产系统里真实存在的需求——排行榜、热搜、监控告警都靠它，而排序是最诚实的暴力。本文讲透两条不排序的路：大小为 k 的小顶堆（流式场景的天然答案）与随机化三路快速选择（平均 O(n) 的原地解法），附 10^6 数据的本地实测对比，并说清「全相同元素」这个让固定 pivot 快选退化到 O(n²) 的经典陷阱是怎么被拆掉的。
