Given the following Karnaugh Map for a Boolean function \( F(w,x,y,z) \): 

Which one or more of the following Boolean expression(s) represent(s) \( F \)?

In a 4-bit ripple counter, if the period of the waveform at the last flip-flop is 64 microseconds, then the frequency of the ripple counter in kHz is ___________. (Answer in integer)

Consider the given sequential circuit designed using D-Flip-flops. The circuit is initialized with some value (initial state). The number of distinct states the circuit will go through before returning back to the initial state is:


 

int main () {
     double a [2]={20.0.25.0},*p,*q,
     p=a;
     q=p+1
      printf (%d, %d, (int) (q-p))
int(*-q-*p);
int g(int p)
{
     printf("%d", p);
     return p;
}
int h(int q)
{
     printf("%d", q);
     return q;
}
void f(int x, int y)
{
     g(x);
     h(y);
}
int main ()
     f(g(10), h(20));
}
What is the o/p printed ? (parameters all evaluated from left to right)
