Calculating and visualizing Kaprekar constant (6174) using R Reference to blog: (https://tomaztsql.wordpress.com/2019/02/20/number-6174-or-kaprekar-constant-in-r/).

Kaprekar number is one of those gems, that makes Mathematics fun. Indian recreational mathematician D.R.Kaprekar, found number 6174 – also known as Kaprekar constant – that will return the subtraction result when following this rules:

1. Take any four-digit number, with minimum of two different numbers (1122 or 5151 or 1001 or 4375 and so on.)
2. Sort the taken number and sort it descending order and ascending order.
3. Subtract the descending number from ascending number.
4. Repeat step 2. and 3. until you get the result 6174

In practice, e.g.: number 5462, the steps would be:

6542 - 2456 = 4086
8640 - 468 = 8172
8721 - 1278 = 7443
7443 - 3447 = 3996
9963 - 3699 = 6264
6642 - 2466 = 4176
7641 - 1467 = 6174
