"KAPREKAR'S CONSTANT" number ( 6174 )

Start with any 4 digit no.
in which not all digits are alike.
Arrange them in descending order.
reverse them to make a new no.
and subtract the new no. from the first no..
If you keep repeating this process with the remainders ,you'll( in 8 or less steps)
arrive at number (6174).

Remember to preserve the zeros.
For example, choose 3524:
 5432 – 2345 = 3087
 8730 – 0378 = 8352
8532 – 2358 = 6174 !!!


note:D.R.Kaprekar is a great indian mathematician.
