Coding Kata简介 如何进行Kata练习 亲身感受 Coding Kata简介 前段时间听到一个比较有意思的概念叫做Coding Kata,今天试了一下来说说一些想法和思考.Kata是一个日语,意思大体上是日本武术的套路,没有找到比较好的中文翻译来解释Coding Kata这个词. Coding Kata是一种练习编程能力的一种方法,它要求程序员在拿到一个简单的联系以后进行重复的编码.比如说,第一次快速的按照需求写出来了能工工作的程序,然后抛弃可以工作的第一个版本,重头开始第二轮的编码,…

超级偶数(SuperEven)是指每一位都是偶数的正整数,例如: 0,2,4,6,8,20,22,24,26,28,40,...,88,200,202,... 要求写一个函数,输入项数n,返回数列第n项的值. 说实话,这个题目整整花了我三天时间去思考(数学比较弱,大神见笑)#手动捂脸#. 其实到最后我还是没有完成这个Kata,因为作者要求用少于30个字符的代码解决,我的解决方案再怎么压缩也100个字符左右了.万念俱灰的我还是决定看别人的答案,发现一共有4个人解出来了,答案都一致,非常精妙.但是吹…
