271. Encode and Decode Strings
Difficulty: Medium
https://leetcode.com/problems/encode-and-decode-strings/

──────────────────────────────────────────────────

Design an algorithm to encode a list of strings to a string. The
encoded string is then sent over the network and is decoded back to
the original list of strings.

Machine 1 (sender) has the function:

string encode(vector<string> strs) {
  // ... your code
  return encoded_string;
}
Machine 2 (receiver) has the function:

vector<string> decode(string s) {
  //... your code
  return strs;
}

So Machine 1 does:

string encoded_string = encode(strs);

and Machine 2 does:

vector<string> strs2 = decode(encoded_string);

strs2 in Machine 2 should be the same as strs in Machine 1.

Implement the encode and decode methods.

You are not allowed to solve the problem using any serialize methods
(such as eval).

 

Example 1:

Input: dummy_input = ["Hello","World"]
Output: ["Hello","World"]
Explanation:
Machine 1:
Codec encoder = new Codec();
String msg = encoder.encode(strs);
Machine 1 ---msg---> Machine 2

Machine 2:
Codec decoder = new Codec();
String[] strs = decoder.decode(msg);

Example 2:

Input: dummy_input = [""]
Output: [""]

 

Constraints:

	• 1 <= strs.length <= 200

	• 0 <= strs[i].length <= 200

• strs[i] contains any possible characters out of 256 valid ASCII
characters.

 

Follow up: Could you write a generalized algorithm to work on any
possible set of characters?
