Continuing with this process of forming and subtracting, we will always arrive at the number 6174.
What are Kaprekar constants and Kaprekar loops? Really cool. 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 $.
Students love Qalaxia as they earn rewards for providing correct answers to quiz questions and for posting good questions for experts to answer.
https://brilliant.org/wiki/kaprekars-constant/. The mathematical proof of the existence of 6174 as the only fixed point number of the algorithm is a bit long and consists in enumerating a few possible cases and proving that only one case has no contradiction.
close, link Then rearrange the digits to get the largest and smallest numbers these digits can make.
Share your knowledge or write an opinion piece. A reasonable person would find this content inappropriate for respectful discourse. The difference between the two is that while PV represents the present value of a sum of money or cash flow, NPV represents the net of all cash inflows and all cash outflows, similar to how the net income of a business after revenue and expenses, or how net benefit is found after evaluating the pros and cons to doing something.
6174 is the Kaprekar Constant.
2) Arrange the digits in ascending and then in descending order to get two four-digit numbers, adding leading zeros if necessary. The range check if value < 1 or value > 9998 could be more Pythonically expressed as if not 1 <= value <= 9998. Sort four digits in descending order and store result in a number “desc”. Thank you !

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.

A set of questions to assess student understanding.
students could build up some form of overview of what happens for a series of 4 digit numbers (this diagram is a subset of the options) there is a fuller picture on Wiki it should take at most 7 iterations (steps) to arrive at Kaprekar's 4-digit constant: 6174 (or 7641 etc)
