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…

这是悦乐书的第221次更新,第233篇原创 01 看题和准备 今天介绍的是LeetCode算法题中Easy级别的第88题(顺位题号是412). 编写一个程序,输出从1到n的数字的字符串表示.但对于三的倍数,它应输出"Fizz"而不是数字,对于五的倍数,应该输出"Buzz". 对于三和五共同的倍数,应输出"FizzBuzz".例如: 输入:n = 15 输出:["1","2","Fizz"…

Description Given number n. Print number from 1 to n. But: when number is divided by 3, print "fizz". when number is divided by 5, print "buzz". when number is divided by both 3 and 5, print "fizz buzz". Example If n = 15, yo…
