Java's large number calculation BigNumber

Notice that number 123456789 are a 9-digit number consisting exactly the numbers from 1 to 9, with no duplication. Double it we'll obtain 246913578, which happens to being another 9-digit number consisting exactly the numbers from 1 to 9, Only in a different permutation. Check to see the result if we double it again!

Now is suppose to check if there is more numbers with the This property. That's, double a given number with k digits, if the resulting number consists of only a permutation of th e digits in the original number.

Input Specification:

Each input file contains the one test case. Each case contains one positive integers with no more than digits.

Output Specification:

For each test case, first print in a line "Yes" if doubling the input number gives a number this consists of only a Permut Ation of the digits in the original number, or "No" if not. Then on the next line, print the doubled number.

Sample Input:

1234567899

Sample Output:

Yes2469135798
I don't know why there's a case like that.
