2, What is the computational complexity of the following function?
// findprimes
// This function will find (and print to the screen) all
// prime numbers up to the input parameter n;
// inputs: integer n
// This is C++ code, but it should read much like Java
void findprimes (int n)
{
int i; int j;
// setting a(0] and a[1) to "not prime"
int a[n] ;
a [0] =0;
a(1) =0; ;
for (i = 2; i< n; i++)
// initialize everything to "prime"; will check later
a[i) - 1;
for (i - 2; i < n; i++)
if (a(i])
for (j = i; (j*i) < n; j++)
%3!
a[i*j]

e of 20
for (i = 2; i < n; i++)
{
//
cout << i << "," << a[i) << endl;
if (ali))
