The days-without-incident counter at your factory has become difficult to interpret.

The counter is a single-digit seven-segment display that you bought cheaply in a second-hand hardware store. Each of its seven segments is either off or on, and a digit is shown by turning on the corresponding segments:

$$$\,$$$ $$$\,$$$ $$$\,$$$ $$$\,$$$ $$$\,$$$

$$$\,$$$ $$$\,$$$ $$$\,$$$ $$$\,$$$

Every morning, the display is reset so that all segments are off. When a digit is entered into the display, every segment belonging to that digit is flipped: from off to on, or from on to off. This worked just fine as long as the counter only ever needed to show a single digit.

However, thanks to your diligent work with safety protocols, the number of days without incident now routinely reaches two-digit numbers. Since the display has room for only one digit, a two-digit number is entered by typing its two digits one after the other, into the same display. This may well flip a particular segment off again.

The number of days without incident is called the streak length $$$s$$$ and satisfies $$$0\leq s\leq 99$$$. It is entered without leading $$$0$$$s, so a single-digit streak length is entered as one digit.

Given the state of the display after the streak length has been entered, determine which values of $$$s$$$ could have produced it.
