121 - Algorithm Interview Question: Nth Fibonacci Number - nth-fibonacci-number.txt

Hi, here's your problem today. This problem was recently asked by Apple:

The Fibonacci sequence is the integer sequence defined by the recurrence relation: F(n) = F(n-1) + F(n-2), where F(0) = 0 and F(1) = 1. In other words, the nth Fibonacci number is the sum of the prior two Fibonacci numbers. Below are the first few values of the sequence:

0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144...

126 - Python才是世界上最好的语言 - python-is-the-best.txt

　　不同的编程有不同的应用场景和不同的使用场合，因此无法全面的评论哪种语言是最好的。但是各种不同的媒介还是每隔一段时间都会发布编程语言的热度排行榜。前不久电气和电子工程师协会（ IEEE）发布了顶级编程语言交互排行榜。Python超越Java高居首位。

　　为什么Python在IEEE Spectrum的调查里面这么受欢迎呢？

　　一个原因就是Python现在已经逐渐受到嵌入式的支持。放在以前，受到嵌入式硬件的限制，一般只能支持一些编译语言。但是现在随着嵌入式硬件变得越来越强大，他的硬件能力足以支撑起Python的运行。而Python对于一些特定的嵌入式应用场景可以非常简单、方便、快速的搭建起可运行系统。因此，Python现在在嵌入式圈子里逐渐得到应用并且火了起来。
