Transformation to odd digits

Consider the following transformation of a positive integer where each of its even digits is replaced by the next higher odd digit. For example, the number $22265$ is transformed to $33375$ while the number $809$ is transformed to $919$ .

Given a sequence of positive integers (i.e., each of them is greater than zero), write a program that outputs their transformation to odd digits as described above.

Input

The input is a sequence of positive integers followed by the special end marker $0$ (which is not part of the sequence).

Output

For each of the elements in the sequence, a line with its transformation to odd digits.
