Encode and Decode Strings
Explore how to encode and decode arrays of strings by converting them into a single string and back using bitwise manipulation. Understand the problem constraints and implement practical solutions to efficiently handle string data for network transmission.
We'll cover the following...
Statement
Create a method, encode, that converts an array of strings into a single string and then sends it over the network. Create another method, decode, that takes the encoded string and converts it back into the original array of strings.
Constraints:
-
strings.length -
strings[i].length strings[i]consist of any possible combinations of characters from 256 valid ASCII characters.
