Encode and Decode Strings

Design an algorithm to encode a list of strings to a single string and decode that single string back to the original list.

The encoded string is sent over the network and decoded on the other side; there is no restriction on the encoding/decoding algorithm. Your encode and decode functions must be inverses of each other.

Example 1

Input: strs = ["neet", "code", "love", "you"]
Output: ["neet", "code", "love", "you"]
Explanation: After encoding and decoding, the original list is recovered exactly.

Example 2

Input: strs = ["we", "say", ":", "yes"]
Output: ["we", "say", ":", "yes"]
Explanation: Special characters like ":" must survive the round-trip without being misinterpreted.

Constraints

• 0 <= strs.length <= 200
• 0 <= strs[i].length <= 200
• strs[i] contains any possible character, including the empty string.
