Structural Design Patterns in Modern C++ - Adding StringInfo for Sharing Internal Strings

The video tutorial discusses optimizing memory usage in string handling by implementing the flyweight pattern. It explains how multiple string instances can share a common buffer to reduce memory consumption. The tutorial introduces the concept of intrinsic state and attributes that can be shared among string instances. It details the creation of a 'string info' structure to manage shared attributes and reference counting. The video also covers the implementation of helper functions and methods to manage string instances efficiently, including the use of unordered maps and reference counting techniques.

Why is it important to keep the length attribute in the string class despite being computable?

Describe the purpose of the find method in the context of unordered maps.

What happens in the release method when the reference count reaches zero?
