The numbers of Kaprekar are the numbers described by the Indian mathematician Kaprekar in 1949. When n squared is taken to the n-1 digit on the left and the n on the right is added to the n-1 digit, the result gives the t number again. Example: 55 is a two-digit number. 552 = 3025, two digits from the right 25, two digits from the left 30. The sum of the two numbers is 30 + 25 = 55, ie the number itself. 1, 9, 45, 55, 99, 297, 703, 999, 2223, 2728, 4879 are also some other Kaprekar numbers.
