kaprekar's constant calculator

First choose a four digit number where the digits are not all the same (that is not 1111, 2222,…). It is important to make the distinction between PV and NPV; while the former is usually associated with learning broad financial concepts and financial calculators, the later generally has more practical uses in everyday life.

Kaprekar then forms a new number $N$ such that $N_2-N_1 = N$ and repeats the process until arriving at a previously found number. The Kaprekar routine from a number $N$ consists of creating 2 other numbers $N_1$ and $N_2$ by arranging the digits of $N$ through sorting by ascending order to $N_1$ and decreasing for $N_2$.

Example: $N = 7533$, $N_1 = 3357$, $N_2 = 7533$, replace $N$ with $7533 - 3357 = 4176$ $N = 4176$, $N_1 = 1467$, $N_2 = 7641$ then replace $N$ with $7641 - 1467 = 6174$ $N = 6174$, $N_1 = 1467$, $N_2 = 7641$ replace $N$ with $7641 - 1467 = 6174$, which creates an infinite loop on the constant 6174, which is the Kaprekar constant for 4 digits. NPV is a common metric used in financial analysis and accounting; examples include the calculation of capital expenditure or depreciation. PV is defined as the value in the present of a sum of money, in contrast to a different value it will have in the future due to it being invested and compound at a certain rate. Log in here.
