You are given a script that simulates $N$ steps of a marker along $x.$ Your task is to compute the

total distance travelled by the marker $($assign the result to d$).$ You should do this by adding

your own lines of code to the existing script. Ideally, you will

add code to line #$3$ to initialize d;

add code to line #$8$ to update $d$;

$($optional$)$ add code at the very end $($line #$10)$ to display d;

Note that the following lines in the template are locked $($you are unable to edit them$)$: $1,2,5,$

$6,7,$ and $9.$

Hint: consider using a built$-$in function called abs for finding the absolute value $($feel free to

look it up using MATLAB Help$).$
