https://leetcode.com/contest/6/problems/convert-a-number-to-hexadecimal/ 分析:10进制转换成16进制,不能用库函数,刚开始,我被误导,一直到考虑负数怎么表示成补码,其实,这个系统已经帮我们做好了,计算机里面就是二进制补码表示的,我们需要做的,就是把数字表示成32位二进制,然后每四位映射成一个16进制数字,最后去掉前导0,然后就ok. 注意:不要被什么正数,负数,0,如何表示成二进制补码吸引注意力. string toHex…

这是悦乐书的第219次更新,第231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86题(顺位题号是405).给定一个整数,写一个算法将其转换为十六进制.对于负整数,使用二进制补码方法.例如: 输入:26 输出:"1a" 输入:-1 输出:"ffffffff" 注意: 十六进制(a-f)中的所有字母必须为小写. 十六进制字符串不得包含额外的前导0.如果数字为零,则由单个零字符"0"表示;否则,十六进制字符串中的第一…
