Class StringArray

The StringArray class implements a memory-efficient array of strings. It stores strings as bytes in a byte array, using UTF-8 encoding, and uses a single byte to mark the end of a string ('\0'). This class provides methods to calculate the size of strings in memory, create StringArray instances from arrays or collections of strings, and retrieve or set strings at specific indices. The internal data structure uses a byte array to store the string data and an integer array to map array indices to offsets in the byte array. Limitations: - The class does not support dynamic resizing of the internal byte array, so the initial size must be sufficient to store all strings. - Once a string is set at a specific index, it cannot be changed or removed. - The class is not thread-safe and should be used with caution in concurrent environments. - Adding strings beyond the allocated memory will result in a runtime exception.
