先上用Python写的十进制转二进制的函数代码: def Dec2Bin(dec): result = '' if dec: result = Dec2Bin(dec//2) return result + str(dec%2) else: return result print(Dec2Bin(62)) 图解此函数执行过程: 文字描述此函数的执行过程: 以十进制数10作为例子来解释递归问题.首先,进入函数Dec2Bin(10),此时参数dec=10,而result接受的是Dec2Bin(5)的
在windows平台上安装python c extension的扩展包是件很痛苦的事情,一般通过安装vc/vs系列来编译C扩展,不过安装包都比较大.或者通过mingw编译,不过有时会在兼容性上出现点问题. 有个好消息就是微软为Python提供了专用的编译器Microsoft Visual C++ Compiler for Python 2.7(包含32位和64位) 下载地址: http://aka.ms/vcpython27 提示:在此感谢@ThunderEX的提醒,setuptools 6.0

Leetcode 67:Add Binary(二进制求和) (python.java) Given two binary strings, return their sum (also a binary string). The input strings are both non-empty and contains only characters 1 or 0. 给定两个二进制字符串,返回他们的和(用二进制表示). 输入为非空字符串且只包含数字 1 和 0. Example 1: Input
