In my understanding, Templates allow us to write a single function or class that works for different data types.
Containers, such as a stack or linked lists, are used to store data, but can store one type of data at a time. To store different types of data in storage, we must write different versions of the same container class. We can keep this code repetition by writing a class template.
I know that it saves the effort of writing part of the programmer. but I want to know that using patterns saves memory or not.
