Problem Statement

You are given a string $S$ consisting of 0, 1, 6, 8, and 9.

Rotate $S$ $180$ degrees and print the result. In other words, apply the following operations on $S$ and print the resulting string:

• Reverse $S$.
• Replace each 0 with a 0, each 1 with a 1, each 6 with a 9, each 8 with an 8, and each 9 with a 6.

Constraints

• 1≤∣S∣≤105
• $S$ consists of 0, 1, 6, 8, and 9.

Sample Input 1

0601889

Sample Output 1

6881090

Rotating 0601889 $180$ degrees results in 6881090.

Sample Input 2

86910

Sample Output 2

01698

Sample Input 3

01010

Sample Output 3

01010

$S$ may remain the same.
