$1)10$ points:

$-$ define a function in the appendix named factorial with the input n and

the output fact

$-$ within the function factorial initialize fact with $1$

$-$ write a loop over i from $1$ to in with increments of $1$ and in each loop

iteration carry out: fact $=$ fact$*$i;

$-$ define a variable n and set it to $5$

$-$ call the function factorial and pass in n as an input and store the

returned vale in the variable result

$-$ display the variable result
