Recursion

What will be the output of the following C program?

void count(int n){
     static int d=1;
     printf("%d ", n);
     printf("%d ", d);
     d++;
     if(n>1) count(n-1);
     printf("%d ", d);
}
void main(){
     count(3);
}

Consider the following program:

int f(int *p, int n)
{
    if (n <= 1) return 0;
    else return max(f(p+1,n-1),p[0]-p[1]);
}
int main()
{
    int a[] = {3,5,2,6,4};
    printf("%d", f(a,5));
}

*Note*: max(x,y) returns the maximum of x and y. The value printed by this program is ________.
