Complete save$\_$dist$\_$list function that saves N distances' values into a file For example,

Integer Array for Distances

Number of Distances to Save

lab$3\_$dist.dat

$[1,1,7,23,-1]$

$4$

$11723$

Note: the NEWLINE character $($at the end of every line$)$ is not visible.

The above example shows that save$\_$dist$\_$list function takes $4$ distances from the distance array, converts integers into ASCII characters, as a result of $"11723"$ in the data$\_$buffer, then makes syscall to write $9$ characters from this string into lab$3\_$dist.dat file.

NOTE: you can safely assume

I. The distances to save are guaranteed positive$/$valid$,$ e$.$g$.$ N$=4,$ the first four numbers in the array must be positive.

Arguments and Given parameters:

$>>$ $a$0$: the address of the string that represents the output file name, "lab$3\_$dist.dat".

Thought before starting to code: How to convert $23$ into $\text{'}2\text{'},\text{'}3\text{'}?$ other examples, $123->\text{'}1\text{'},$

$\text{'}2\text{'},\text{'}3\text{'}?$

$>>$ $a$1$: the base address of an integer array that stores distances

$>>$ $a$2$: the number of distances to save from an integer array

$>>$ data$\_$buffer: the buffer that you use to hold data for file read$/$write $($MAXIMUM: $300$ bytes$)$
