<p>两年前,我在力扣上分享了《剑指 Offer》系列题解受到了许多朋友的喜爱与支持。在此期间我回答了众多读者的评论问题其中最常见的一个问题是“如何入门学习算法”。我逐渐也对这个问题产生了浓厚的兴趣。</p>
<p>两眼一抹黑地刷题似乎是最受欢迎的方法,简单直接且有效。然而,刷题就如同玩“扫雷”游戏,自学能力强的同学能够顺利地将地雷逐个排掉,而基础不足的同学很可能被炸的满头是包,并在挫折中步步退缩。通读教材书籍也是一种常见做法,但对于面向求职的同学来说,毕业季、投递简历、准备笔试面试已经占据了大部分精力,厚重的书籍往往变成了一项艰巨的挑战。</p>
<p>如果你也面临类似的困扰,那么很幸运这本书找到了你。本书是我对此问题的给出的答案,虽然不一定正确,但至少是一次积极的尝试。这本书虽然不足以让你直接拿到 Offer ,但会引导你探索数据结构与算法的“知识地图”,带你了解不同“地雷”的形状大小和分布位置,让你掌握各种“排雷方法”。有了这些本领,相信你可以更加自如地应对刷题和阅读文献,逐步构建起完整的知识体系。</p>
