提出问题 一个网友的博客,记录他在一次面试时,碰到面试官要求他在白板上用TensorFlow写一个简单的网络实现异或(XOR)功能.这个本身并不难,单层感知器不能解决异或问题是学习神经网络中的一个常识,而简单的两层神经网络却能将其轻易解决.但这个问题的难处在于,我们接触TensorFlow通常直接拿来写CNN,或者其他的深度学习相关的网络了,而实现这种简单网络,基本上从未做过:更何况,要求在白板上写出来,如果想bug free,并不是容易的事儿啊. 数据 李宏毅老师对数据进行了如下分析 对数字1…

Write a program that outputs the string representation of numbers from 1 to n. But for multiples of three it should output “Fizz” instead of the number and for the multiples of five output “Buzz”. For numbers which are multiples of both three and fiv…

------------------------ AC代码: class Solution { /** * param n: As description. * return: A list of strings. */ public ArrayList<String> fizzBuzz(int n) { ArrayList<String> results = new ArrayList<String>(); for (int i = 1; i <= n; i++…

下面是AC代码,C++风格: class Solution { public: vector<string> fizzBuzz(int N) { vector<string> Answer; ;i <= N;i++) { == ) { Answer.push_back("fizz buzz"); } == ) { Answer.push_back("fizz"); } == ) { Answer.push_back("buzz…

写一段程序从1打印到100,但是遇到3的倍数时打印Fizz,遇到5的倍数时打印Buzz,遇到即是3的倍数同时也是5的倍数时打印FizzBuzz.例如: 1 2 Fizz 4 Buzz Fizz 7 8 Fizz Buzz 11 Fizz 13 14 FizzBuzz 16 17 Fizz 19 Buzz ... 等等,直到 100…

看到一篇文章上说,很多貌似看过很多本编程书的童鞋连简单的fizz buzz测试都完不成. 不知道fizz buzz test为何物的,建议自行搜之. 测试要求是,编写满足以下条件的代码: Write a program that prints the numbers from 1 to 100. But for multiples of three print "Fizz" instead of the number which are multiples of both three…
