Solution: Encode and Decode Strings
On this page

Problem Statement

Design an algorithm to implement these two functions: one that can effectively convert the list of strings to a single string (encoding) and another that can revert this single string back to the original list (decoding).

Constraints:

  • You cannot use any serialization methods such as eval.
  • The goal is to ensure that after encoding and then decoding, the output is identical to the input.

Machine 1 (Sender):

  • encode(List<String> strs): Takes a list of strings and converts it to a single encoded string.

Machine 2 (Receiver):

  • `decode(String s)
