Hello 算法 Kotlin 语言版 作者：靳宇栋（@krahets） 代码审阅：陈东辉（@curtishd） Release 1.1.0 2024‑04‑15 序 两年前，我在力扣上分享了“剑指 Offer”系列题解，受到了许多读者的鼓励和支持。在与读者交流期间，我 最常被问的一个问题是“如何入门算法”。逐渐地，我对这个问题产生了浓厚的兴趣。 两眼一抹黑地刷题似乎是最受欢迎的方法 . 11 1.2 算法是什么 . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 13 1.3 小结 . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 15 第 2 章 复杂度分析 多种编程语言的实现。 约定俗成的简称 在实际讨论时，我们通常会将“数据结构与算法”简称为“算法”。比如众所周知的 LeetCode 算法题 目，实际上同时考查数据结构和算法两方面的知识。 1.3 小结 ‧ 算法在日常生活中无处不在，并不是遥不可及的高深知识。实际上，我们已经在不知不觉中学会了许多 算法，用以解决生活中的大小问题。 ‧ 查字典的原理与二分查找算法相一致。二分查找算法体现了分而治之的重要算法思想。
