vector<string> strs2 = decode(encoded_string); strs2in Machine 2 should be the same asstrsin Machine 1. Implement theencodeanddecodemethods. 题解: encode 时维护一个stringbuilder, 对于每一个string, sb append 该string长度 + "/" + string内容. decode 时开始index = 0, while index < s.lengt...
https://leetcode.com/problems/encode-and-decode-strings/description/ image.png 这道题是序列化反序列化LIST<STRING> 因为STRING可能可以包含任何字符。所以我采用的是JDK的做法。先存STRING的长度,然后打一个空格,随后存STRING。 publicclassCodec{// Encodes a list of strings to a single string.public Str...
271. Encode and Decode Strings Encode and Decode Strings 编码解码字符串 这道题只需要用\转义,用/分割就可以了,可能需要注意判断decode的时候如果为"/"则为{""} 注意:不能用/转义,用/分割。这样的话无法无脑解决["",""]这种情况,或者说///就没办法确定是什么了。 classCodec{public:// Encodes a lis...
271. Encode and Decode Strings /** 271. Encode and Decode Strings * 2016-6-25 by Mingyang * 这道题很酷的地方就是选择一种存储方式可以有效地存储string,我一开始就想到了存长度加string的方法 * 这个题用了一个indexof的API, * public int indexOf(String str,int fromIndex)...

which can be easily transmitted over networks that only support ASCII characters. In JavaScript, we can use the built-inbtoa()andatob()functions to encode and decode strings toBase64. These functions are simple to use and provide a quick way to convert data to a format that can be easily...
So if this is so easy to decode then why use it to obfuscate malicious code? Great question! The answer is becauseBase64is not only OS agnostic but, as it turns out, very robust and relatively easy to over engineer. Sooner or later you will run into something that fails to decode: ...
In order for a string to be read from all computers sometimes it is useful to encode and decode it. This can be easily achieved using the JavaScript built-in es
