<p>如果将最终写好运行的程序比作战场，我们码农便是指挥作战的将军，而我们所写的代码便是士兵和武器。</p>
<p><strong>那么数据结构和算法是什么？答曰：兵法！</strong></p>
<p>我们可以不看兵法在战场上肉搏，如此，可能会胜利，可能会失败。即使胜利，可能也会付出巨大的代价。我们写程序亦然：没有看过数据结构和算法，有时面对问题可能会没有任何思路，不知如何下手去解决；大部分时间可能解决了问题，可是对程序运行的效率和开销没有意识，性能低下；有时会借助别人开发的利器暂时解决了问题，可是遇到性能瓶颈的时候，又不知该如何进行针对性的优化。</p>
<p>如果我们常看兵法，便可做到胸有成竹，有时会事半功倍！同样，如果我们常看数据结构与算法，我们写程序时也能游刃有余、明察秋毫，遇到问题时亦能入木三分、迎刃而解。</p>
<p><strong>故，数据结构和算法是一名程序开发人员的必备基本功，不是一朝一夕就能练成绝世高手的。冰冻三尺非一日之寒，需要我们平时不断的主动去学习积累。</strong></p>
<p><strong>通过三天的学习，我们希望让大家能理解其概念，掌握常用的数据结构和算法。</strong></p>
