**How do I find my Kaprekar number?**

Calculate the length of square, that is, the number of digits in square. Iterate over the square and in every iteration, divide the square into two parts. Add both the parts and compare the sum with the original number. If the sum and number are both equal, then the number is Kaprekar number and terminate the loop.

### What is the 1089 Trick?

The mystery is this: first, take any three digit number, where the first and last digits differ by two or more and reverse the number to produce a new one. Then subtract the smaller from the larger producing another new number. If you reverse this number and this time add the two, the result will always be 1089.
