Fun Fact
A number with n unique digits can be shuffled into up to n! (factorial) different arrangements-meaning just 10 digits can produce over 3.6 million unique permutations.
Historical Context
Digit shuffling is rooted in the mathematical study of permutations, formally developed in the 18th and 19th centuries. Modern algorithms like the Fisher-Yates shuffle, introduced in 1938, remain the gold standard for unbiased randomization and are widely used in computing today.
