QR code is a common image encoding technology widely used in business, marketing and information transfer fields. The process of generating a QR code involves processing and arranging the coded data, and therefore involves different combinations. In this article, we will explore the number of combinations of QR codes and provide the corresponding source code implementation.
In order to understand the number of combinations of QR codes, we need to first understand the basic structure of QR codes. A standard QR code usually consists of black and white squares, each square is called a module. According to the specifications of QR codes, the arrangement of modules can be arbitrary, but it is also subject to some restrictions, such as the position of positioning marks and check digits.
Suppose we use a simplified model where the QR code consists of nxn modules. Each module can be black or white, so there are two possible states. Then, the total number of combinations can be calculated by 2 to the n^2 power.
Let's look at a simple example, assuming we use a 3 x 3 QR code. According to the above formula, the number of combinations of this QR code is 2 (3 2) = 2^9 = 512.
Now, let us use the Python programming language to implement a program that counts the number of QR code combinations:

return 2**(
