浮动的气泡-Floating bubbles

无论是体系结构还是指令集，大家或多或少都应该对X86汇编有些了解，而对于嵌入式领域已被广泛采用的ARM 处理器，了解的可能并不多。-Whether it is architecture or instruction set, we should be more or less a compilation of the X86, some understanding, and for the field of embedded has been widely used in ARM processors, may not be more understanding.

joseph环。任务：编号是1，2，……，n的n个人按照顺时针方向围坐一圈，每个人只有一个密码（正整数）。一开始任选一个正整数作为报数上限值m，从第一个人开始顺时针方向自1开始顺序报数，报到m时停止报数。报m的人出列，将他的密码作为新的m值，从他在顺时针方向的下一个人开始重新从1开始报数，如此下去，直到所有人全部出列为止-joseph ring. Tasks: number is 1,2, ... ..., n of the n individuals in accordance with the clockwise direction around a circle, each person there is only one password (positive integer). One began to choose a positive integer as the number of reported upper limit m, from the first individual to start a clockwise direction since the beginning of the order of one off, back off m stop. Reported m the person out of his password as the new m value, in a clockwise direction from his next re-started from the beginning of one off, it goes on like this until all the column until all

应用背景Windows系统，安装了perl环境。可以根据您的搜索条件或者提供的GI号，从NCBI上自动下载超大序列。能自动下载超过50000条以上的核酸或蛋白序列。有时候需要根据自己提供的GI号从NCBI上下载需要的基因或蛋白序列，这个小程序可实现自动下载。在windows操作系统下即可轻松完成，直接双击程序，自动运行下载序列。关键技术放在任何文件夹双击运行。相当于在NCBI首页上查询某物种的基因或蛋白序列，然后自动下载保存为fasta格式。根据使用目的修改脚本。使用方法如下：查询核酸序列：NCBI--左上选Nucleotide--右边输入要查询的物种和限制条件，比如番茄tomato mRNA，出来很多序列，在右下方Search details处，可看到查询条件其实是 ("Solanum lycopersicum"[Organism] OR tomato[All Fields]) AND mRNA[All Fields]，复制这个查询条件，粘贴到脚本的第12行$query = ""Solanum lycopersicum"[orgn]"的单引号里面覆盖"Solanum lycopersicum"[orgn]，脚本14行$url = $base . "esearch.fcgi?db=protein&term=$query&usehistory=y";里面的db=后面的protein改成Nucleotide，32行$efetch_url = $base ."efetch.fcgi?db=protein&WebEnv=$web"里面的protein也改成Nucleotide。修改这三处之后即可查询得到fasta格式序列。如果查询蛋白序列，按上述方法得到查询条件粘到$query后面，把后面的库db改成protein。查询其它库依此类推。
