The following function is a part of some class. Assume ‘n’ is a positive integer. Answer the given questions along with dry run / working,
int unknown (int n)
{ int i, k;
if (n%2 = = 0)
{
i = n/2; k=1;
}
else
{
k=n;
n--;
i=n/2;
}
while (i > 0)
{
k=k*i*n;
i--;
n--;
}
return k;
}
(i) What will be returned by unknown(5)?
(ii) What will be returned by unknown(6)?
(iii) What is being computed by unknown (int n)?
