A **spy number** is a type of number with a unique property that makes it interesting in number theory. Here's the breakdown of the concept:

A **spy number** is a positive integer that can be split into two parts in such a way that:

1. The sum of the digits of the first part equals the sum of the digits of the second part.
2. The sum of the digits of the entire number is divisible by the number of digits in the number.

For example, take the number **123**:

- Split it into **1** and **23**.
- The sum of the digits of **1** is 1.
- The sum of the digits of **23** is 5 (2 + 3).
- The sum of all digits (1 + 2 + 3) is 6.
- The sum of all digits (6) is divisible by the number of digits (3) in the number.

Thus, **123** could be considered a spy number.

These numbers have a fun and somewhat mysterious quality to them, where the "spying" involves how the parts of the number work together mathematically!
