4. [Programming Assignment] Consider the following recursive C function that computes floor (log2 k) for any positive global integer variable k 2 1 unsigned int k-47; mainO printf("The floor of log2 of %d is %d", k, floor-log-2(k)); int floor-log-2 (int n) if (n-1) return(0); else return(1 + floor-log-2(n >> 1); //Right-shift performs integer division by 2 (a) Draw a representation of the stack frame for floor-log-20. Show what each field is intended to hold (by name)
