PHP,适应于上帖简单加密后的密文复制代码代码如下:php
AWK,通用格式复制代码代码如下:#!/bin/awk function compress(str, _ARGVEND_, str_out, str_len, i, s, l) {str_out = "";str_len = length(str);s = "";l = 1;for(i =1; i if(substr(str, i, 1) == s) l++;else {if(s != "") {if(l > 1) str_out=str_out""l str_out=str_out""s;}s = substr(str, i, 1);l = 1;}}return str_out;}function uncompress(str, _ARGVEND_, str_out, str_len, i, c) {str_out = "";str_len = length(str);for(i =1; i c = 0;while(substr(str, i, 1)~/[0-9]/) {c = c*10+substr(str, i, 1);i++;}if(c while(c--) str_out = str_out""substr(str, i, 1);}return str_out;}
