Luke Skywalker gave Chewbacca an integer number $*x*$. Chewbacca isn't good at numbers but he loves inverting digits in them. Inverting digit $*t*$ means replacing it with digit $9 - *t*$.

Help Chewbacca to transform the initial number $*x*$ to the minimum possible positive number by inverting some (possibly, zero) digits. The decimal representation of the final number shouldn't start with a zero.

Input

The first line contains a single integer $*x*$ $(1 ≤ *x* ≤ 10^{18})$ — the number that Luke Skywalker gave to Chewbacca.

Output

Print the minimum possible positive number that Chewbacca can obtain after inverting some digits. The number shouldn't contain leading zeroes.
