$(1$ point$)$

Assume $n$ is a positive integer. Count the number of operations in the loop below:

$x$:$=6$

for $i$:$={|}_{{?}_{?}}\frac{n}{2_{{?}_{?}}}|ton$

$,x$:$=n*i+n*x-4*i$

next $i$

for $i$:$={|}_{{?}_{?}}\frac{n}{2_{{?}_{?}}}|$ to $n$

next $i$

The number of operations performed by this algorithm depends on whether $n$ is even or odd.

Case $1$: $n$ is even

There are

operations performed in each run of the loop and the loop runs

times, so the total number of operations performed in this loop is

Case $2$: $n$ is odd

There are

operations performed in each run of the loop and the loop runs

times, so the total number of operations performed in this loop is
