[Explanation]
・This tool evaluates the complexity of a 4-digit number by calculating the entropy of its power spectrum.
・To calculate the power spectrum, the Fourier transform is performed after arranging the digits 0 through 9 at equal intervals on the complex unit circle.
・The larger the resulting value, the more complex the entered number is;
the minimum value is 0% (e.g., input 0000), the maximum value is 100% (e.g., input 3237), and the average value is 74%.
