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 that add
up to the original number again. For
instance, 45 is a Kaprekar number, because
45² = 2025 and 20 + 25 = 45. The Kaprekar
numbers are named after D. R. Kaprekar.
