Split the string representation of the square into two parts, and . Ask Question Asked 4 years, 1 month ago. For each n >= 1 , we disallow 10 n as a Kaprekar number since it is the vacuous solution to (1) and (2) when N = 10 n. decimal numbers); if you can, show that Kaprekar numbers exist in other bases too. Anybody can answer

A Kaprekar number is a number whose square when divided into two parts and such that sum of parts is equal to the original number and none of the parts has value 0. Learn more about Stack Overflow the company Detailed answers to any questions you might have For this purpose, do the following: Find all Kaprekar numbers for base 17 between 1 and 1,000,000 (one million);

The universal Kaprekar number 1 corresponds to the unitary divisor 1 of 10 n - 1, which is why we allow unity as a Kaprekar number. Upcoming Events

The numbers are named after D. R. Kaprekar. Discuss the workings and policies of this site In number theory, Kaprekar's routine is an iterative algorithm that, with each iteration, takes a natural number in a given number base, creates two new numbers by sorting the digits of its number by descending and ascending order, and subtracts the second from the first to yield the natural number for the next iteration. It only takes a minute to sign up.I am stuck in this hackerrank problem where it asks to output "By convention, the second part may start with the digit 0, but must be nonzero. site design / logo © 2020 Stack Exchange Inc; user contributions licensed under Mathematics Stack Exchange works best with JavaScript enabled The concept of Kaprekar numbers is not limited to base 10 (i.e. The best answers are voted up and rise to the top A Kaprekar number for a given base is a non-negative integer, the representation of whose square in that base can be split into two parts that add up to the original number again. Please write to us at contribute@geeksforgeeks.org to report any issue with the above content. It is not a Kaprekar number even if sum of 100 + 0 is 100. In mathematics, a Kaprekar number for a given base is a non-negative integer, the representation of whose square in that base can be split into two parts—either or both of which may include leading zeroes—that add up to the original number.

A modified Kaprekar number is a positive whole number with a special property. It is named after its inventor, the Indian mathematician D. R. Kaprekar. We square to arrive at a number that is either digits long or digits long. Active 4 years, 1 month ago. Viewed 2k times 2 $\begingroup$ I am stuck in this hackerrank problem where it asks to output Kaprekar numbers, and since $10^2 = 100$, and it can be represented as $10+0$, where could I be wrong here? In mathematics, a [[natural 55r]] in a given number base is a p {\displaystyle p} -Kaprekar number if the representation of its square in that base can be split into two parts, where the second part has p {\displaystyle p} digits, that add up to the original number.
