Each digit will be $5$ pixels wide and $7$ pixels tall. She decides to save space by storing the pixels for each digit using run$-$length encoding $($RLE$).$

RLE is a data compression technique that replaces "runs" $($sequences of bits with the same value$)$ with a number representing the length of the run.

Here's the RLE for one of the digits:

$1,3,1$

$0,1,3,1$

$0,1,3,1$

$1,3,1$

$,1,3,1$

$,1,3,1$

$1,3,1$
