A mathematician delves into the fascinating mystery of the number 6174, known as Kaprekar’s constant. This seemingly ordinary number hides a remarkable property: when you take any four-digit number (with at least two different digits), rearrange its digits in descending and ascending order, then subtract the smaller number from the larger one, you’ll always arrive at 6174 after a few iterations. Once you reach it, the process locks in—6174 repeats indefinitely. This mathematical phenomenon, disc
