Elevator Ride

Description
Every time Katya enters the elevator, she sees the reflection of the floor number in the mirror.
The floor number is displayed on a panel, which shows the digits as shown in the picture.
Because the floor number is visible in the mirror, its reflection is reversed with respect to the vertical axis: the order of the digits is reversed and the digits appear as their reflections. However, if a digit $x$ after reflection completely coincides with another digit $y$, the brain perceives it as $y$. But if it does not match any other digit, despite being reflected, the brain perceives $x$ as $x$.
What number will Katya see when she enters the elevator, if it is known that she lives on the $k$-th floor.
Given an integer $k$ ($1 \le k \le 10^{18}$) — the floor where Katya lives.
Output a single number that Katya will see in the mirror, without leading zeros.
