A9844. Chewbaсca and Number

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.

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

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