morse code,摩斯电码,是一种时通时断的信号代码,通过不同的排列顺序来表达不同的英文字母.数字和标点符号. 摩斯电码,是一种早期的数字化通信形式,但是它不同于现代只使用0和1两种状态的二进制代码,它的代码包括5种: 点.划.点和划之间的停顿.每个字符间短的停顿(在点和划之间).每个词之间中等的停顿以及句子之间长的停顿. 下图为morse code的密码本 通过密码本,我们可以写1个测试程序 懂了这些,morse code基本入门了. 接着,说一下电报机原理 首先,电报机是由发报机与收报机…

摩尔斯电码,在早期的"生产斗争"生活中,扮演了很重要的角色,作为一种信息编码标准,摩尔斯电码拥有其他编码方案无法超越的长久生命.摩尔斯电码在海事通讯中被作为国际标准一直使用到1999年.不过随着科技的发展,最终还是倒在了历史的车轮下(PS:等等,为何这么熟悉??观众:好一片根正苗红的*文啊,啊啊啊啊),1997年,当法国海军停止使用摩尔斯电码时,发送的最后一条消息是:“所有人注意,这是我们在永远沉寂之前最后的一声呐喊!”. 任何关于Morse code可拓展的咨询,请移步维基百科:摩尔…

练习算法绕不开的一个网站就是力扣,很多小伙伴为了拿到大厂 offer,刷题都刷到吐了. 然而如果直接在 LeetCode 上写代码,那是很痛苦的一件事,那就相当于用 txt 写代码一样,没有 IDE 的各种功能. VS Code 的 LeetCode 插件帮助我们解决了这一问题.以下是官方教程:https://github.com/jdneo/vscode-leetcode/blob/master/docs/README_zh-CN.md. 其实这个教程已经很详细了,我只是在个别地方做了补充.…
