有没有办法压缩字符串(使用 gem 或标准库)以便我可以获得字符串的压缩结果？示例:
"hello world".zip #=> zipped version of string
此外，如果有人可以将其包含在他们的解决方案中，那么减压会很好。
最佳答案
您可以使用 Zlib
>> require 'zlib'
=> true
>> s = "this is a long string with many many many many repetition"
=> "this is a long string with many many many many repetition"
>> s.size
=> 57
>> cs = Zlib.deflate(s)
=> "x\x9C+\xC9\xC8,V\x00\xA2D\x85\x9C\xFC\xBCt\x85\xE2\x92\xA2L U\x9EY\x92\xA1\x90\x9B\x98W\x89N\x14\xA5\x16\xA4\x96d\x96d\xE6\xE7\x01\x00\\?\x15P"
>> cs.size
=> 48
>> is = Zlib.inflate(cs)
=> "this is a long string with many many many many repetition"
