Could you explain what the term 'unpacking' means in programming?

In programming, the term "unpacking" refers to the process of extracting elements from collections, arrays, or other data structures and assigning them to individual variables.

In C#, unpacking is often encountered when working with tuples or arrays. For example:

var tuple = (1, "text", true);
var (number, text, flag) = tuple;
Console.WriteLine(number); // 1
Console.WriteLine(text);   // text
Console.WriteLine(flag);   // True

Here, the tuple is unpacked into separate variables. This simplifies working with multiple values returned from a method and makes the code more readable.
